The C Line (formerly the Green Line from 1995 to 2020) is a 17.8-mile (28.6 km) light rail line running between the Los Angeles neighborhood of Westchester and the city of Norwalk in southwestern Los Angeles County, California. It is one of six lines forming the Los Angeles Metro Rail system and opened on August 12, 1995. Along the route, the line also serves the cities of Downey, Hawthorne, and Lynwood, as well as several unincorporated communities in the South Los Angeles region including Athens, Del Aire, and Willowbrook.

For a majority of its route, the C Line runs within the median strip of Interstate 105. When built, its western segment was an elevated leg that diverted from the 105 to the southwest and terminated in Redondo Beach. In 2024 and 2025, the western end of the C Line was reconfigured, and is now routed northwards to LAX/Metro Transit Center.
