The Riverside Yacht Club, Connecticut is a private, recreational yacht club located in the Riverside neighborhood of Greenwich, Connecticut, with access to Long Island Sound.

[2][3] Using his own money and waterfront property, Tyson built the original Victorian-style clubhouse in 1889 on the eastern shore of Cos Cob Harbor near the entrance of the Mianus River.

[4] For a short period during the early 1890s, the club met in winter quarters in New York City, and by the late 1920s, the club membership had purchased the property from the Tyson estate.

[2] On September 21, 1938, the 1938 New England hurricane caused the main and junior clubhouses to flood, with no damage to sailing vessels.

[4] Some vessels, but not the clubhouse, were damaged as a result of the 1944 Great Atlantic hurricane.
