The Marciano Art Foundation (formally named the Maurice and Paul Marciano Art Foundation) was a non-profit arts foundation located on Wilshire Boulevard in the Mid-Wilshire neighborhood of Los Angeles, California. It was established by the co-founders of Guess, Maurice Marciano and Paul Marciano. The Marcianos opened the museum on May 25, 2017 as an exhibition space to display their 1,500-piece collection of contemporary art. The museum closed indefinitely in November 2019 after workers attempted to unionize. The Marciano Foundation released a statement a month later that the closure was permanent.
