Metro-North Railroad's Waterbury Branch is a branch of the New Haven Line, running north from a junction east of Stratford, Connecticut to Waterbury. Originally built as the Naugatuck Railroad, it once continued north to Winsted, Connecticut. The part north of Waterbury is now leased from CDOT by the Railroad Museum of New England, which operates excursion trains from Thomaston station; that part is still called the Naugatuck Railroad reporting mark|NAUG. The trackage ends in Torrington, Connecticut but Metro North service on the branch ends at Waterbury.

The stations on the Waterbury Branch have two major differences in comparison to most other stations in the Metro-North system. None have ticket machines, making it possible to buy fares on board with no surcharge. Also, outside of Waterbury, all stations have low-level platforms (with the exception of Merritt 7 on the Danbury Branch, no other regular stations east of the Hudson have such platforms).
