The United States Post Office and Sub-Treasury Building (demolished 1929) was a public building on Post Office Square in Boston, Massachusetts. Built in the late nineteenth century, it was the first post office building in the city to be owned by the United States federal government. The John W. McCormack Post Office and Courthouse now stands on its former site.
