The Mullin Automotive Museum was a privately owned automobile museum in Oxnard, California, US. Established in 2010, it displayed the personal car collection of businessman and philanthropist Peter W. Mullin. The museum had a large collection of vintage Bugattis and other early 20th century French cars. Many of the cars were fully restored and able to be driven, while others were left purposely unrestored to preserve their history. After the founder’s death in September 2023, the museum closed on February 10, 2024. Many of the cars from the collection were subsequently auctioned off, while some were transferred to other collections, such as the Hispano-Suiza Dubonnet Xenia, which went to the Petersen Automotive Museum.
