Anacostia Community Museum

The Anacostia Community Museum (known colloquially as the ACM) is a community museum in the Anacostia neighborhood of Washington, D.C., in the United States. It is one of twenty museums under the umbrella of the Smithsonian Institution and was the first federally funded community museum in the United States. The museum, founded in 1967, was created with the intention to bring aspects of the Smithsonian museums, located on the National Mall, to the Anacostia neighborhood, with the hope that community members from the neighborhood would visit the main Smithsonian museums. It became federally funded in 1970 and focuses on the community in and around Anacostia in its exhibitions. This museum also houses a library.

In 2025, President Donald Trump proposed a federal budget that would discontinue funding for the institution. The amount would equal 60% of the museum's total budget and its proposed withdrawal threatens the continuity of the institution.
