Sebastian Gladstone is a contemporary art gallery founded by dealer Sebastian Gladstone, who began selling art through estate sales during the pandemic before opening a gallery in Los Angeles and rebranding under his own name after a 2022 move to a larger space in the city's Melrose Hill neighborhood. The gallery expanded to New York with a Tribeca location and, in September 2025, opened a second Los Angeles space in Hollywood. Its program combines living artists with estates, favoring practices that resist easy categorization; recent exhibitions have included painter Cosima zu Knyphausen and artist Nick Angelo.
