Ecstasy is a 1979 play by British playwright Mike Leigh with a six-character cast.

Jean is a suicidal garage attendant who sleeps with unsuitable men, like Roy, drinks heavily and has abortions.

Her friend from Birmingham, Dawn, who has had three children, brings back her husband Mick, an Irish labourer, and his quiet friend, Len, to Jean's bleak Kilburn bedsitter, - 'their second act ensemble trumpets the dark night of the soul, in what is at once one of the best and gloomiest party scenes in contemporary drama.

The production was designed by Alison Chitty, and the cast comprised Sheila Kelley as Jean, Ron Cook as Roy, Rachel Davies as Val, Julie Walters as Dawn, Stephen Rea as Mick, and Jim Broadbent as Len.

A new production directed by Leigh, and starring Sian Brooke, Daniel Coonan, Claire Louise Cordwell, Allen Leech, Sinead Matthews, and Craig Parkinson opened on 10 March 2011 at the Hampstead Theatre,[2] and transferred to the Duchess Theatre in Covent Garden on 12 April 2011.
