The Silver Line, also known as the Cotton Belt Rail Line, is an under construction 26-mile (42 km) hybrid rail (light rail with some features similar to commuter rail) service traversing Tarrant, Dallas, and Collin counties and in the U.S. state of Texas operated by Dallas Area Rapid Transit (DART). The line will provide service from Dallas's northeast suburbs of Plano, Richardson, and Addison to Dallas/Fort Worth International Airport Terminal B.

According to DART, the Silver Line is "designed to provide a high-speed, reliable transit option for residents and commuters with connections to the existing and planned transit systems" and aims to improve transit travel times by providing an alternative to congested roadway networks.

The working name for the project, the Cotton Belt Rail Line, comes from a former subsidiary of the Southern Pacific Railroad, the St. Louis Southwestern Railway, commonly known as the Cotton Belt, which previously owned the line. DART purchased the right-of-way in 1990 for future transit use.
