The Emlen Physick Estate is a Victorian house museum in Cape May, New Jersey, located at 1048 Washington Street. The 18-room mansion, attributed to acclaimed American architect Frank Furness, was built in 1879 for Dr. Emlen Physick Jr. (1855-1916), descendant of a well-known Philadelphia family, his widowed mother, Mrs. Ralston, and maiden Aunt Emilie. The mansion is closely related to Furness's Knowlton Mansion (1880–81) in Northeast Philadelphia.
