In Seine-et-Marne (77), in Nemours, the Saint-Jean Fair 2026 is taking over the town center from Thursday 18 to Sunday 21 June 2026. Free and open to all, this fair-exhibition is one of the summer’s most anticipated events in southern Île-de-France, expected to draw tens of thousands of visitors over four days. Born in 1948, it sits at the edge of Île-de-France, at the crossroads of four departments, which has long given it a reach that extends well beyond the town limits.
Every year, nearly 200 exhibitors gather around four major areas of activity, making this fair far more than just a market. You’ll find stands dedicated to home and renovation, construction, new energies, kitchens, gardens, and pools, as well as spaces devoted to the gastronomy and local products, fashion, the automotive sector, or even leisure. An auto show takes to Gambetta Avenue each year during the four days of the fair, showcasing technologically advanced sedans and popular city cars.
What makes this event special is its very strong local roots. A market of local producers and artisans d'art is highlighted, driven by the Communauté de communes du Pays de Nemours: fresh produce from nearby farms, artisanal know-how, live tastings… It’s a place to wander, to shop, but above all to meet the people who keep the region alive. The fair’s concept, centered on meeting and tasting, lets visitors discover produits viticoles et gastronomiques presented by the manufacturers, producteurs and distributors themselves, a way to put faces behind the labels.
On the entertainment front, the vibe is genuinely festive. Brass bands, animations nocturnes, mascots and défilés keep the days lively, with the funfair right on the other side, on the Champ de Mars. Families with kids will find plenty to enjoy here, from carousels to on-site dining and a whole array of stalls. It’s one of those events where you pop by for an hour and end up spending the whole day.
Yes—and that’s one of its main strengths. The Saint-Jean fair and expo is free and open to everyone. So families can go without worrying about costs, which helps explain its enduring popularity since 1948. For the 77th edition in 2026, organizers promise a program that measures up to the best of past years. All details on exhibitors and the full schedule can be found on the official Nemours Fair site.
This event welcomes both local families from the Pays de Nemours and visitors from across Île-de-France, curious about local produce, bargain hunters, or simply looking for a friendly outing for a June weekend. And if you’d like to extend the day, know that the musée de la Préhistoire d'Île-de-France, housed right in the town, is well worth a visit.
Our take: a popular, locally rooted gathering that succeeds in blending tradition and novelty without taking itself too seriously. Perfect for a family outing or a get-together with friends at the start of summer.
Who is this for: families, the curious, fans of handmade and local products, and anyone looking for a free, lively outing in Seine-et-Marne.
