The Immigration Museum is a museum primarily displaying Australia's immigration history. It is located on Flinders Street in Melbourne, Victoria, in the Old Customs House. It is famous for its most important space, the Long Room, which is a notable piece of Renaissance Revival architecture.
The museum was founded in 1998, and is a division of Museums Victoria, which administers the cultural and scientific collections of the State of Victoria. Its sister museums are Melbourne Museum and Scienceworks Museum.
In addition to its work on documenting immigration history, the museum also hosts various travelling exhibitions, and also provides educational programs.
