Captain George Mainwaring (/ˈmænərɪŋ/) is the bank manager and Home Guard platoon commander portrayed by Arthur Lowe on the BBC television sitcom Dad's Army, set in the fictional seaside town of Walmington-on-Sea during the Second World War. He has become widely accepted and regarded as a classic British comic character owing to the popularity of both Dad's Army and Lowe's portrayal of him.

In the 2016 film based on the sitcom, Mainwaring is played by Toby Jones.

Mainwaring was born in 1885 to Edmund Mainwaring and is a pompous, blustering figure with an overdeveloped sense of his importance, fuelled by his social status in Walmington-on-Sea as the bank manager and his status as Captain and commander of the local Home Guard volunteer unit. He became commander of his home guard unit by saying that he had served as a captain in the last British conflict which he obviously made up because it says that he served in 1919 which was after the "last conflict" (WW1) had ended. He was later officially designated as the Captain by the GHQ, in the episode Room at the Bottom, after his brief reduction in rank. Despite his claims that he was born into a well-to-do family, it is revealed that he is actually of working class origins and his father was a heavy drinker, as is his profligate brother, Barry, who is a travelling salesman specialising in novelty toys. He has many redeeming qualities: he is essentially brave, loyal and industrious, generally kind-hearted beneath the bluster and unfailingly patriotic.
