The Union Street Festival is one of San Francisco’s largest and most iconic neighborhood festivals, attracting 75,000 attendees across two full days in the affluent Cow Hollow and Marina Districts. Produced by Sunset Mercantile in partnership with the Union Street Merchants Association, the festival transforms one of SF’s most recognizable retail corridors into an open air celebration of live music, food and drink, local shopping, interactive activities, and cultural entertainment. This event anchors the start of San Francisco’s summer festival season and offers brands high visibility in a vibrant, upscale environment. The festival draws a younger, affluent, highly educated demographic, including white collar professionals, families, singles, and avid lifestyle consumers who frequent boutique retail, outdoor dining, wellness brands, and contemporary entertainment. Attendees engage with craft cocktails and mocktails, local brews, artisan vendors, and features such as the festival’s waiters race, live screen printing activations, wellness integrations, and hands on makers programming. This creates a dynamic mix of cultural appeal and purchasing power unmatched by most neighborhood events. Celebrating its 49th annual edition, the Union Street Festival has become a cornerstone of San Francisco’s cultural identity and a major driver of community engagement in the Marina. With large format stages, premium food and beverage zones, high profile activation footprints, and a consistent draw of 75,000 plus attendees, the event provides an exceptional platform for brands looking to connect with an audience that values premium experiences, local artistry, wellness, and innovative consumer products. Its location in one of the city’s most desirable retail corridors ensures sustained dwell time and repeat engagement throughout the weekend.
