Under Milk Wood is a 1954 radio drama by Welsh poet Dylan Thomas, commissioned by the BBC and later adapted for the stage. A film version, Under Milk Wood directed by Andrew Sinclair, was released in 1972, and another adaptation of the play, directed by Pip Broughton, was staged for television for the 60 anniversary in 2014.

An omniscient narrator invites the audience to listen to the dreams and innermost thoughts of the inhabitants of the fictional small Welsh fishing village, Llareggub.

They include Mrs. Ogmore-Pritchard, relentlessly nagging her two dead husbands; Captain Cat, reliving his seafaring times; the two Mrs. Dai Breads; Organ Morgan, obsessed with his music; and Polly Garter, pining for her dead lover. Later, the town awakens and, aware now of how their feelings affect whatever they do, we watch them go about their daily business.
