AMSAT-OSCAR 6 (also called AMSAT-OSCAR C, AO-6, Amsat P2A or simply OSCAR 6) was an American amateur radio satellite.

It was launched on October 15, 1972, on a Delta 300 rocket from Vandenberg Space Force Base, together with the NOAA-2. It was the first satellite developed by Radio Amateur Satellite Corporation (AMSAT).

The first two-satellite communication was established in 1975 via OSCAR 4. The satellite was decommissioned on June 21, 1977 due to failure of their batteries.
