U.S. Route 1 (US 1) in the U.S. state of Connecticut is a major east–west U.S. Route along Long Island Sound. It has been replaced by Interstate 95 (I-95) as a through route, which it closely parallels, and now primarily serves as a local business route. Despite its largely east–west orientation, it is part of a north–south route and is mostly signed north–south.

Most of US 1 through Connecticut encompasses its predecessor, the Boston Post Road, and, in many towns, it is still named Boston Post Road (or Post Road).
