A Family At War is a British drama series that aired on ITV from 1970 to 1972. It was created by John Finch and made by Granada Television for ITV. The original producer was Richard Doubleday, and with 13 directors during the series. The series examined the lives of the lower middle-class Ashton family of the city of Liverpool and their experiences from 1938 and through the Second World War.

Fifty-two episodes were produced, all but eight of them in colour. Episodes numbers 25 to 32 were recorded in black and white because of the ITV Colour Strike. The memorable theme tune is from the end of the First Movement (Allegro) of Vaughan Williams's Sixth Symphony. The programme opening titles show a scene of a beach with a child's sand castle, with Union Flag flying, slowly being approached by the encroaching tide, symbolic of a beleaguered Britain standing alone in 1940–1941.
