Downtown Santa Monica station is an at-grade light rail station in the Los Angeles Metro Rail system. It is located near the intersection of 4th Street and Colorado Avenue in downtown Santa Monica, California. It is the E Line's western terminus.

The station is located in Downtown Santa Monica, off-street in the block bounded by 4th and 5th Streets, Colorado Avenue, and the 10 Freeway. The site is located in the midst of Santa Monica's Civic Center. The block was formerly the location of a Sears auto center, which was demolished in 2010 to make way for the station.

A trip from downtown Santa Monica to downtown Los Angeles takes 47 minutes.

Originally opened in 1875 for the Los Angeles and Independence Railroad with subsequent stops along the coast, the station eventually served Pacific Electric passenger and freight service into the 1980's and was completely rebuilt when converted to light rail service.
