The Wooster Square Historic District encompasses much of the Wooster Square neighborhood of New Haven, Connecticut. Centered on a rectangular park named in honor of General David Wooster, the area was developed as a residential neighborhood beginning in the 1820s, and was by the 1840s a desirable area to live, with many high-quality Greek Revival homes. In the 1950s the area was the subject of a major community-led preservation effort that drew national attention. The district was listed on the National Register of Historic Places in 1971.
