Brix Smith (born Laura Elisse Salenger; November 12, 1962) is an American singer and guitarist, best known as the lead guitarist and a major songwriter for the English post-punk band the Fall during two stints in the band (1983–1989, and 1994–1996).

Acknowledging her importance to the band, and noting she co-wrote several songs for the band's most widely acclaimed album This Nation's Saving Grace (1985), some critics break the Fall's career and evolution into the pre-Brix years, the Brix years, and the post-Brix years.

She is currently the lead vocalist and guitarist with Brix & the Extricated, along with brothers Steve and Paul Hanley, both of whom were long time musicians in the Fall. She published her memoir The Rise, The Fall, And The Rise with Faber & Faber in May 2016, noting that "writing the book freed my creativity to play again."
