The Shell House is a historic home located at 26 Westland Drive on East Island in Glen Cove in Nassau County, New York. It was built as a guest cottage and home of the yacht captain on the Matinecock Point Estate of J. P. Morgan, Jr. (1867–1943). The house is composed of a small, Norman style core dated to the mid-19th century, with a large Tudor Revival addition built about 1910. Also on the property are the remains of a pier and a poured concrete and cinder block wall. It was listed on the National Register of Historic Places in 1988. The house was rebuilt in the late-2010s.
