St. Louis Annual Events: A Season-by-Season Guide to the City's Best Festivals
Revised July 24, 2026
What are the best annual events and festivals in St. Louis?
St. Louis marks its seasons with mostly-free annual festivals: Soulard Mardi Gras (late winter); the Downtown and Dogtown St. Patrick’s Day parades (March); Shakespeare in the Park and PrideFest (late spring/June); the Fourth of July on the Gateway Arch grounds; Festival of Nations, the Japanese Festival, and Big Muddy Blues (late summer); the Saint Louis Art Fair and Great Forest Park Balloon Race (September); Soulard Oktoberfest (October); and the Ameren Thanks-For-Giving Parade (late November), which bridges into the winter holidays. Confirm each year’s exact date before you go.

St. Louis runs on exactly that kind of calendar. From the first beads of a late-winter Mardi Gras to the smell of bratwurst at an October Oktoberfest, the city marks its seasons with festivals that are, more often than not, free and open to anyone who shows up.
Here is a season-by-season guide to the annual events St. Louis throws every single year — the traditions worth building a weekend around, whether you’ve lived here for decades or just unpacked the last box. Dates shift a little year to year, so treat this as the shape of the calendar and confirm the exact weekend before you go.
Late winter: Mardi Gras season
St. Louis takes Mardi Gras seriously — fittingly, for a city with French roots. The heart of it is Soulard Mardi Gras, one of the largest Mardi Gras celebrations in the country, unfolding over several weeks in the historic Soulard neighborhood and peaking with a massive Grand Parade the Saturday before Fat Tuesday. There are family-friendly events earlier in the season and a rowdier street party on parade day; either way, it’s the city’s first big outdoor gathering of the year and a genuine only-in-St.-Louis experience. Bundle up, get there early for parking, and let the beads fly.
Spring: parades and green rivers of people
March belongs to St. Patrick. St. Louis runs two beloved St. Patrick’s Day parades, and locals have strong opinions about them. The Downtown St. Patrick’s Day Parade is the big, decades-old civic one along Market Street, with floats, bands, and a run to match. Out in Dogtown — the historically Irish neighborhood near Forest Park — the Ancient Order of Hibernians parade on March 17 is the neighborhood-party version, a wall-to-wall street celebration that’s as much block party as parade. Pick your style, wear green, and plan your ride: both draw enormous crowds.
Late spring and early summer: culture in the park
As the weather turns, St. Louis heads to Forest Park and downtown. The St. Louis Shakespeare Festival’s “Shakespeare in the Park” stages a free, professional production in Forest Park’s Shakespeare Glen across late May and June — bring a blanket, a picnic, and a bottle of wine. In late June, PrideFest, the region’s largest Pride celebration, fills downtown with a parade and festival. It’s a stretch of the calendar defined by long evenings, free entertainment, and the city rediscovering its outdoor self.
Summer: fireworks over the Arch
The Fourth of July is a marquee event here. The annual Fourth of July celebration on the Gateway Arch grounds (the long-running successor to Fair Saint Louis) packs the riverfront and downtown with live music, an air show, and one of the biggest fireworks displays in the Midwest, framed by the Arch itself. It’s hot, it’s crowded, and it’s worth it — stake out a spot early, hydrate, and enjoy a genuinely spectacular backdrop. Smaller municipal fireworks light up communities all across the metro the same week if downtown feels like too much.
Late summer: the world comes to St. Louis
Late August and early September are the city’s most gloriously international stretch. The Festival of Nations in Tower Grove Park — a free, decades-old celebration put on by the International Institute — gathers dozens of cultures for food stalls, music, and dance, and it is a food-lover’s dream. Over Labor Day weekend, the Japanese Festival at the Missouri Botanical Garden (running since the 1970s) turns the world-class Japanese Garden into a showcase of taiko drumming, tea ceremonies, and lantern-lit evenings, while the Big Muddy Blues Festival brings free live blues to Laclede’s Landing. Between them, you could eat and listen your way around the globe without leaving town.
Early fall: art, balloons, and beer
September and October are arguably peak festival season. The Saint Louis Art Fair transforms downtown Clayton into one of the top-ranked juried art fairs in the country, free to browse. Nearby, the Great Forest Park Balloon Race — and its can’t-miss Friday-night Balloon Glow, when the balloons light up after dark — is a free, decades-old St. Louis tradition that draws a hundred thousand people to Forest Park. Then the season turns to beer: Soulard Oktoberfest brings German food, music, and steins to Soulard Market Park, one of several Oktoberfests across the metro. Cooler air, big crowds, and a lot to do outdoors before winter.
Late fall: the bridge to the holidays
As the leaves drop, downtown kicks off the holiday season with the Ameren Thanks-For-Giving Parade — a giant-balloon, marching-band Thanksgiving parade the Saturday before the holiday, ending at Kiener Plaza and rolling straight into the downtown Winterfest festivities. From there, the metro lights up for the winter holidays: for that whole stretch — the light displays, the Christmas markets, New Year’s Eve — see our dedicated seasonal guides, which pick up right where this calendar leaves off.
How to make the most of St. Louis’s event calendar
A few habits turn a good festival day into a great one. Confirm the exact date the week before — most of these move by a weekend or two each year. Plan the parking or take transit for the big draws (Mardi Gras, the parades, July 4, the Balloon Race all snarl traffic), and consider MetroLink for downtown events. Get there early for anything free and popular, both for a good spot and easier parking. Bring cash for food and craft vendors, sunscreen and water in summer, and layers in the shoulder seasons. And follow the event’s official page or the venue for the current year’s schedule — lineups and hours are set fresh each season even when the tradition itself is a fixture.
Why the city’s festivals are worth showing up for
There’s a reason St. Louisans organize their calendars around these events. Most are free, which makes them some of the best entertainment value in the region. They’re how a big metro of distinct neighborhoods actually comes together — Soulard, Dogtown, Tower Grove, Clayton, and downtown each get their moment to host the whole city. And they’re the fastest way for a newcomer to feel like a local: show up to a couple of these, and the year stops feeling like a stranger’s calendar and starts feeling like yours. Pick one from the next season on the horizon, and go.
Festivals by neighborhood: who hosts what
One of the charms of the St. Louis calendar is that the celebrations are spread across the city’s distinct neighborhoods, each with a signature event it’s known for. Soulard owns the bookends of the outdoor year — Mardi Gras in late winter and Oktoberfest in the fall — both anchored at its historic market. Dogtown is synonymous with its St. Patrick’s Day street party. Tower Grove Park hosts the international food-and-culture sprawl of Festival of Nations. Forest Park is the setting for Shakespeare in the Park and the Great Forest Park Balloon Race. Clayton’s downtown becomes a top-tier art fair each September. And the Gateway Arch grounds and downtown host the civic big-hitters: the July 4 fireworks, PrideFest, and the Thanks-For-Giving Parade. If you want to get to know St. Louis’s neighborhoods, following the festival calendar is one of the best ways to do it — each event is also an introduction to the place that throws it.
The free-festival advantage (and how to do it on a budget)
It’s worth saying plainly: a remarkable number of these events cost nothing to attend. Festival of Nations, the Great Forest Park Balloon Race and Balloon Glow, the Saint Louis Art Fair, Shakespeare in the Park, the parades, and Big Muddy Blues are all free at the gate. That makes St. Louis’s festival season one of the best entertainment values anywhere — you can fill a whole summer of weekends without buying a ticket. To do it smart: bring your own water and snacks where allowed (and cash for the food you can’t resist), arrive early to skip the worst parking, and check each event’s page for free-admission details versus paid add-ons like reserved seating, rides, or beer gardens. For families especially, the combination of free entry and genuinely world-class programming — a professional Shakespeare production, a hundred balloons rising over Forest Park, dozens of cultures under one park’s trees — is hard to beat anywhere in the country.
Building your own St. Louis tradition
The locals who love this city most tend to have their handful of non-negotiable events — the ones they go to every single year, rain or shine, until they become as much a part of the season as the weather. Maybe it’s the Balloon Glow every September, or Festival of Nations for the food, or the Dogtown parade with the same crew. The invitation here is simple: pick one or two from this calendar, go this year, and go again next year. That’s how a new arrival turns into a St. Louisan — not all at once, but one beloved annual tradition at a time, until the whole year has a familiar, welcome shape to it. And the beauty of a calendar this full is that there’s almost always something on the horizon: finish one season’s festival and the next is only a few weeks out, which is a quietly wonderful thing to realize about the place you live.
A quick, honest note on a changing calendar
Festivals aren’t permanent fixtures, and it’s worth going in with clear eyes. Beloved events do sometimes pause, move, or end — rising costs, staffing, and safety logistics have all reshaped the local calendar in recent years, and a festival that ran for a decade can go on hiatus without much warning. That’s exactly why the single most useful habit for any of these is to check the event’s official page or social media before you make plans, rather than assuming last year’s date and location still hold. The events in this guide are the sturdy, long-running anchors of the St. Louis year — the ones most likely to be there season after season — but even they set fresh details annually. A two-minute check saves a wasted trip, and it’s the price of admission for a city whose calendar is alive and always evolving.
