The Silver Line, also known as the Cotton Belt Rail Line, is a 26-mile (42 km) hybrid rail service in Tarrant, Dallas, and Collin counties and in the U.S. state of Texas operated by Dallas Area Rapid Transit (DART). The line provides service from Dallas's northern suburbs of Plano, Richardson, Addison, and Carrollton 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, came from 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.
