Brix Smith 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.

The Fall were an English post-punk group, formed in 1976 in Prestwich, Greater Manchester. They underwent many line-up changes, with vocalist and founder Mark E. Smith as the only constant member. The Fall's long-term musicians included drummers Paul Hanley, Simon Wolstencroft and Karl Burns; guitarists Craig Scanlon, Marc Riley, and Brix Smith; and bassist Steve Hanley, whose melodic, circular bass lines are widely credited with shaping the band's sound from early 1980s albums such as Hex Enduction Hour to the late 1990s.
