The Upland–San Bernardino Line was an interurban line operated by the Pacific Electric Railway between Downtown Los Angeles and San Bernardino, California. This line also had shorter services which terminated before the end of the line at Baldwin Park, Covina, and San Dimas. Though service along this line in its entirety was discontinued in November 1941, it stands as the fourth-longest rapid transit line in American history, after the Sacramento Northern Railway's Chico and Colusa services, and the Pacific Electric's own Riverside–Rialto Line.

The right of way has been partially converted to a rail trail. Further segments of the line remain active. The western segment was rebuilt to run in the median strip of the San Bernardino Freeway with the locomotive-hauled Metrolink San Bernardino Line operating over the line since 1992. A segment near its western end around Rialto is also active.
