Ecstasy is the second mini album by the alternative rock band My Bloody Valentine, released on 23 November 1987 on Lazy Records. Released in a limited edition of 3,000 copies, it was the band's final release for Lazy Records and second to feature vocalist and guitarist Bilinda Butcher, who was recruited in April 1987 following the departure of original My Bloody Valentine vocalist David Conway. Ecstasy followed the noise pop and twee pop standards of My Bloody Valentine's earlier releases for the label, drawing influence from various artists including The Jesus and Mary Chain, Love and The Byrds, and the album distanced the band further from their earlier post-punk and gothic rock sound.

My Bloody Valentine are an Irish-English alternative rock band formed in Dublin in 1983 and consisting since 1987 of founding members Kevin Shields and Colm Ó Cíosóig, with Bilinda Butcher and Debbie Googe (bass). Often cited as a pioneering act in the shoegaze genre, their sound is characterized by dissonant guitar textures, subdued and androgynous vocals, and unorthodox production techniques.
