The Cape Codder was a seasonal passenger train operated by Amtrak between New York City and Hyannis, Massachusetts, on Cape Cod. It operated during the summer between 1986 and 1996. It was the first regular service from New York to the Cape since 1964. The New York, New Haven and Hartford Railroad previously had operated a train under this name until 1958.

Cape Cod is an arm-shaped peninsula extending into the Atlantic Ocean from the southeastern corner of Massachusetts, in the northeastern United States. Its historic, maritime character and ample beaches attract heavy tourism during the summer months. The name Cape Cod, coined in 1602 by Bartholomew Gosnold, is the ninth oldest English place-name in the U.S.
