This is a complete episode list for the BBC television series Secret Army, which ran for three series from 7 September 1977 until 15 December 1979.
The series follows the members of a Belgian secret group 'Lifeline', dedicated to enabling Allied airmen to escape to Britain, usually after they had been shot down by the Luftwaffe. Following the timeline of the Second World War, the series shows its impact on the people of Belgium, but also features the attempts of the German Nazi occupiers of Belgium to capture the airmen and to expose and exact retribution on those helping them.
43 episodes of Secret Army were produced; however, the final episode "What Did You Do In The War, Daddy?" has never been broadcast.
