Every June the Upland Lemon Festival takes over the streets of Historic Downtown Upland, a free three-day street party with live music, a carnival midway and food trucks on every block. The 2026 edition, the festival's 29th since it debuted in 1997, drew 120,000 people across June 5 to 7. This is a family crowd. Admission is free and the festival is all ages, so parents, kids, teens and grandparents share the streets, with a Kids Zone, carnival rides and food competitions built for them, and Metrolink's Upland Station sits a short walk from the grounds. Lemon Idol, an on-stage solo vocal contest, and on-stage karaoke put locals in the spotlight. The 2026 program packed more than 50 performances onto five stages, among them Citrus Grove, Pucker Up Pavilion, Lemon Peel Pavilion Gazebo and Lemon Tree, with tribute headliners including Journey USA, So Petty, Uptown Funk and Stevie Nicks Illusion. More than 200 vendors and food trucks lined the streets, with a Crafters Corner and a Non-Profit Row. Metrolink promoted the 2026 festival to its riders with a 20% weekend pass offer. Brands already use the festival to meet the region. 2026 sponsors included Spectrum, Ford of Upland, Metrolink, BeatBox, Surfside and Tequila Cabal, with Ovation School for the Performing Arts presenting Lemon Idol and Historic Downtown Upland presenting the Gazebo Stage. The festival is produced by Soundskilz in partnership with the City of Upland. The Custom package is $5,000. It includes the festival's highest-visibility placement, which is limited in availability, a product display area, a product sampling zone, social media posts and perimeter and stage-side signage. The festival team shapes the mix around your goals.
