History

The term "Cos Cob" comes from the Coe family that settled in the area in 1641. During their time, a wall, known as a "cob", was built on the shoreline by Robert Coe to protect the land he gave to his brother. Henceforth, the place was known as Coe's Cob, later becoming Cos Cob.

The community is situated on Cos Cob Harbor, a sheltered area on the north side of Long Island Sound. Cos Cob's role as a commercial shipping port, supplying potatoes and apples to New York City, disappeared with the appearance of the railroad and damming of the Mianus River. The river is now one source of the town's drinking water.

From 1883 to 1885, the official post office name of Cos Cob was Bayport.
