Fumed Oak is a short play in two scenes by Noël Coward, one of ten that make up Tonight at 8.30, a cycle written to be performed across three evenings. Coward billed the work as an "unpleasant comedy in two scenes". The play concerns a downtrodden, middle-aged salesman who, having saved up enough money to cut all ties, walks out on his wife, mother-in-law and "horrible adenoidal daughter", having first told all three what he thinks of them.
