The Dr. Harrison A. Tucker Cottage is a historic summer cottage at 61 Ocean Avenue in Oak Bluffs, Massachusetts. The cottage took shape in the 1870s as a combination of several smaller structures that were joined together by an addition. Doctor Tucker was a resident of Cottage City, as Oak Bluffs was then known, and invited Ulysses S. Grant during his time there. Tucker was also a leading figure in the Oak Bluffs Land and Wharf Company, which spearheaded development of the town outside the Methodist meeting camp known as Wesleyan Grove. The house was listed on the National Register of Historic Places in 1990, for its association with Dr. Tucker, and as one of the most elaborate Victorian houses in the town.
