Sing Sing Museum or the Sing Sing Prison Museum is a proposed museum in the original power house at the northern end of Sing Sing prison in New York state. The museum will tell the story of incarceration in America and Sing Sing's part of that story. Following a series of delays, programming and the initial exhibition is planned for 2025, the prison's bicentennial year.
Historic Hudson River Towns, the agency developing the latest efforts to create the museum, has been working to redevelop the ground floor former power plant, which powered Old Sparky. While plans for the museum date back to the early 200s, if not earlier, efforts began again in earnest in 2014–2015. There are also discussions to use the original cell block, which survived a fire, to tell the prison's story.
