Wallace Leslie Lawler (15 March 1912 – 28 September 1972) was a British Liberal politician.
He was elected a Member of Parliament (MP) by gaining Birmingham, Ladywood from Labour at a by-election on 26 June 1969.
However, Lawler only served for one year, as Labour's Doris Fisher regained the seat from him at the 1970 general election.
He was the last Liberal to serve as a Member of Parliament in Birmingham, until John Hemming of the successor Liberal Democrats gained Birmingham, Yardley in 2005.
