Intelsat 504, previously named Intelsat V F-4, was a communications satellite operated by Intelsat. Launched in 1982, it was the fourth of fifteen Intelsat V satellites to be launched. The Intelsat V series was constructed by Ford Aerospace, based on the Intelsat-V satellite bus.

Intelsat V F-4 was part of an advanced series of satellites designed to provide greater telecommunications capacity for Intelsat's global network. The satellite was deactivated on November 1995.

The satellite was successfully launched into space on March 5, 1982, at 00:23 UTC, by means of an Atlas SLV-3D Centaur-D1AR vehicle from the Cape Canaveral Air Force Station, Florida, United States. It had a launch mass of 1,928 kg. The Intelsat 504 was equipped with 4 Ku-band transponders more 21 C-band transponders for 12,000 audio circuits and 2 TV channels.
