What Is the Union Street Festival?
The Union Street Festival is a free, all-ages annual street fair held along the 1800 to 2200 blocks of Union Street in San Francisco's Cow Hollow neighborhood. Organized by Sunset Mercantile SF, the festival draws together an impressive lineup of local vendors, artists, live music acts, food and beverage offerings, and community programming across multiple city blocks.
The street closes entirely to traffic for the duration of the event, creating a pedestrian-friendly environment where attendees can browse, eat, listen to live music, and soak in the atmosphere of one of San Francisco's most beloved neighborhoods at a leisurely pace.
Art, Vendors & Live Music
The vendor experience at the Union Street Festival is one of its strongest draws. Dozens of independent makers and retailers line the street with vibrant clothing, handcrafted jewelry, original artwork, and specialty goods — the kind of curated, independent retail energy that defines San Francisco's best neighborhood shopping corridors.
Live music performances run throughout the day across multiple stages, keeping the energy lively from opening to close. It is the kind of programming that holds its own alongside the city's broader performing arts culture, from the grandeur of Davies Symphony Hall to the neighborhood street stages that make San Francisco's community festival scene so distinctive.

Mural Art & Creative Installations
The art programming is one of the Union Street Festival's most memorable features. Mural artwork and collaborative painting installations add a visual dimension that goes well beyond a standard street fair, turning the event into a genuine celebration of San Francisco's thriving creative community. The festival sits naturally within a city that takes public art seriously — from the galleries of the de Young Museum to the rotating exhibitions of the Asian Art Museum.
Food, Drinks & Festive Atmosphere
The Union Street Festival delivers on the culinary front as well. Expect a wide variety of food vendors representing diverse cuisines alongside festival favorites. Craft beverages — including wine slushies and cold beer — are available throughout the event, making it as enjoyable for adults looking to relax as it is for families spending the afternoon together.
The festival is explicitly family and pet-friendly, and the relaxed, welcoming atmosphere makes it one of the most accessible and enjoyable free events on the San Francisco calendar. It sits naturally alongside other beloved neighborhood celebrations like the Downtown First Thursdays street party and the Inner Sunset Flea Market as a cornerstone of the city's community event culture.
