The Maritime Museum of San Diego, established in 1948, preserves one of the largest collections of historic sea vessels in the United States. Located on the San Diego Bay, the centerpiece of the museum's collection is the Star of India, an 1863 iron bark. The museum maintains the MacMullen Library and Research Archives aboard the 1898 ferryboat Berkeley. The museum also publishes the quarterly peer-reviewed journal Mains'l Haul: A Journal of Pacific Maritime History.
The Maritime Museum is located on the west side of North Harbor Drive, between the ends of Ash Street and Grape Street, south of San Diego International Airport.
