Penelope Houston (born December 17, 1958) is an American singer-songwriter best known as the singer for the San Francisco-based punk rock band the Avengers.

Following the group's demise in 1979, Houston moved first to Los Angeles to work in film and video with The Screamers and director Rene Daalder, then to England where she collaborated with Howard Devoto on his post-Magazine projects.

In 1986, she was featured alongside Tomata du Plenty of The Screamers in the punk rock musical Population: 1.

[3] By 1996 she had toured Europe extensively, signed with WEA Germany (Warner Brothers) and earned numerous awards with the dozen albums, which blended influences of punk, folk, rock, blues and Americana into her dark unique acoustic sound.

Shortly after the release of Pale Green Girl, Houston and original guitarist Greg Ingraham recreated the Avengers, adding bassist Joel Reader (formerly of The Mr. T Experience, and The Plus Ones) and drummer Luis Illades (of Pansy Division, formerly also of The Plus Ones) to round out the lineup.
