An American Family is an American television documentary filmed from May 30 through December 31, 1971, and first aired in the United States on the Public Broadcasting Service (PBS) from January 11, 1973, to March 29, 1973. 12 hour-long episodes aired Thursday nights at 9:00 p.m., edited down from about 300 hours of raw footage.

The groundbreaking documentary is considered the first "reality" series on American television. It was originally intended as a chronicle of the daily life of the Louds, an upper middle class family in Santa Barbara, California, but ended up documenting the break-up of the family via the separation and subsequent divorce of parents Bill and Pat Loud.

A year after this program was broadcast, the BBC in 1974 filmed its own similar 12-episode program, called The Family, focusing on the working-class Wilkins family, of Reading, Berkshire, England.
