The C Line (formerly the Green Line from 1995 to 2020) is a 19.3-mile (31.1 km) light rail line running between the Los Angeles neighborhood of Westchester and the city of Norwalk within 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. The fully grade-separated route (essentially a light metro) runs mainly in the median strip of Interstate 105 (the Century Freeway) for its latitude portion and in a mixture of viaducts, embankments, and an open trench for its western leg. A free shuttle bus to Los Angeles International Airport (LAX) is available at Aviation/LAX station.

On November 3, 2024, the C and K lines underwent service changes to accommodate pre-revenue testing at the upcoming LAX/Metro Transit Center station, scheduled to open in 2025. The C Line's western terminus was redirected to Aviation/Century station and the southern segment of the K Line was created between Aviation/Century station and Redondo Beach station. Once LAX/Metro Transit Center station opens, the C Line will terminate at this station, and the K Line will operate as a single, continuous service through it. The LAX Automated People Mover, which will offer a connection to the airport's terminals, will begin service at LAX/Metro Transit Center station in 2026.
