Twice or three times a summer, the grounds of the Racine County Fairgrounds at 19805 Durand Avenue transform into the Union Grove Wisconsin Flea Market, an open-air event where dozens of independent vendors spread out secondhand goods, vintage finds, antiques, homemade products, and collectibles under the open sky. Unlike a permanent thrift store or a mall of fixed booths, this market exists only on select Saturdays each season, with the 2026 dates including May 2, June 27, and August 22, so shoppers need to plan around the calendar rather than dropping in whenever the mood strikes. That scheduled rhythm is part of what keeps the event feeling fresh: vendors and inventory rotate from date to date, and the fairgrounds setting gives sellers room to spread out that a typical indoor market cannot match.
The market is produced by Zurko Promotions, a promotions company that has organized flea markets, antique shows, and similar events across the Midwest for more than five decades, and that experience shows in how the event is run. Vendors are not required to reserve space in advance; they are simply admitted to set up at daybreak on market days, an old-school, first-come approach that keeps the event accessible to small local dealers and casual sellers rather than favoring only large, established antique businesses. The organizers have specifically positioned the market as a home for genuine local sellers rather than what they describe as a lineup of practically commercial run booths, and shoppers consistently mention the friendly atmosphere, fair pricing, and generously spaced vendor rows in their feedback, a rare combination at larger regional flea markets where aisles can feel cramped and impersonal.
Because it is held on fairground property, the market comes with practical amenities: food trucks are typically on site to keep visitors fed through a long morning of browsing, and the open layout accommodates everything from small tables of glassware and collectibles to larger furniture and tool vendors. The event occasionally expands beyond a standard flea market day, pairing the vendor lineup with extras like a classic car cruise-in, which draws an additional crowd of car enthusiasts alongside the usual bargain hunters and adds another reason for repeat visitors to check the calendar each season. For treasure hunters willing to arrive early, the daybreak vendor setup means the very first hour often has the best selection before popular items get picked over.
Located in Union Grove, a small Racine County village roughly midway between Milwaukee and the Illinois state line, the fairgrounds site is an easy drive for shoppers throughout southeastern Wisconsin and northern Illinois looking for a full morning of secondhand browsing rather than a quick stop. Anyone chasing vintage decor, everyday collectibles, or simply the thrill of not knowing what a table might hold will find the format well suited to patient, unhurried searching across a wide outdoor space. In short, the Union Grove Wisconsin Flea Market is a seasonal, Zurko Promotions-run open-air vendor market at the Racine County Fairgrounds offering secondhand goods, antiques, and collectibles on select Saturdays throughout the year.
