My Lisa Karolina Nilsson (born 13 August 1970) is a Swedish singer.

She was discovered by the producer William (Billy) Butt and she is perhaps best known in Sweden for her 1992 hit, Himlen runt hörnet, written by Mauro Scocco and Johan Ekelund.

She has released four subsequent albums, Till Morelia in 1995, Viva in 2000, Små rum in 2002 and Hotel Vermont 609 in 2006, all in Swedish.

A greatest hits compilation, Samlade sånger followed in 2003 and contained two new songs.

Nilsson's style ranges from out and out pop music to soul-inflected ballads and dance tracks on her earlier albums to a more mature jazz feel in her more recent work, perhaps reflecting familial connections as her father Gösta Nilsson is a jazz pianist.
