Cannondale station is a commuter rail station on the Danbury Branch of the Metro-North Railroad's New Haven Line, located in the Cannondale neighborhood of Wilton, Connecticut. The station building was added to the National Register of Historic Places in 1992 as part of the Cannondale Historic District.

The Danbury Branch is a diesel branch of the Metro-North Railroad's New Haven Line in the U.S. state of Connecticut, running from downtown Norwalk north to Danbury. It opened in 1852 as the Danbury and Norwalk Railroad. Until the early 1970s, passenger service continued north from Danbury to Canaan, Connecticut, and Pittsfield, Massachusetts. Metro-North took over operation of the line from Conrail in 1983, and the modern-day branch is mostly single-tracked.
