Lincoln Experimental Satellite 4, also known as LES-4, was a communications satellite, the fourth of nine in the Lincoln Experimental Satellite, and the first of the series designed for operations at geosynchronous altitudes. Launched by the United States Air Force (USAF) on 21 December 1965, it demonstrated many then-advanced technologies including active use of the military's SHF (super high frequency) band (7 to 8 GHz) to service hundreds of users.

Mimo że nie osiągnął zaplanowanej orbity geostacjonarnej z powodu awarii członu Transtage, pomyślnie przetestował wiele urządzeń i technologii telekomunikacyjnych.Satelita spłonął w górnych warstwach atmosfery 1 sierpnia 1977 roku.
