Fox-1Cliff, AO-95 or AMSAT OSCAR 95 is an American amateur radio satellite.

Fox-1Cliff is a 1U CubeSat built by AMSAT-NA that carries a single-channel transponder for mode U/V in FM.

Fox-1Cliff was launched on 3 December, 2018 via Falcon 9 Block 5 from Vandenberg Air Force Base, California, United States.

In 2016, it was renamed Fox-1Cliff in honor of Cliff Buttschardt, a long time member of AMSAT and a contributor to the project, who died earlier that year.
