The West Santa Ana Branch is a rail right of way formerly used by the Pacific Electric's (PE) Santa Ana route in Los Angeles County and Orange County in Southern California. The Los Angeles County Metropolitan Transportation Authority (Metro) owns the segment of the right-of-way in Los Angeles County, and the Orange County Transportation Authority (OCTA) owns the segment in Orange County.

The line runs from the Watts Towers in the city of Los Angeles, southeast to the intersection of 4th Street and Santa Ana Boulevard in downtown Santa Ana. A two-mile (3.2 km) portion of it is occupied by Interstate 105 and the C Line. The right-of-way runs nearly straight on a diagonal between the two cities, in contrast to the cardinal grid of Orange County.
