This Happy Breed is a play by Noël Coward. It was written in 1939 but, because of the outbreak of World War II, it was not staged until 1942, when it was performed on alternating nights with another Coward play, Present Laughter. The two plays later alternated with Coward's Blithe Spirit. The title, a reference to the English people, is a phrase from John of Gaunt's monologue in Act II, Scene 1 of William Shakespeare's Richard II.
