A raisin is a dried grape. Raisins are produced in many regions of the world and may be eaten raw or used in cooking, baking and brewing. In the United Kingdom, Ireland, New Zealand and Australia the word "raisin" is reserved for the dark-coloured dried large grape, with "sultana" being a golden-coloured dried grape, and "currant" being a dried small Black Corinth seedless grape.

Raisin is a musical theatre adaptation of the Lorraine Hansberry play A Raisin in the Sun, with songs by Judd Woldin and Robert Brittan, and a book by Robert Nemiroff (who was Hansberry's former husband) and Charlotte Zaltzberg.
