Laurence John Tully (30 July 1917 – 27 June 1981) was an Australian politician and a member of the New South Wales Legislative Assembly from 1946 until 1965.
He was educated at St Patrick's College, Goulburn and the law faculty of the University of Sydney.
During World War Two, he served with the Royal Australian Air Force.
After an unsuccessful campaign in the seat of Temora in 1944, Tully was elected to the parliament as the Labor member for Goulburn at the 1946 by-election caused by the resignation of his father.
He was briefly the Acting Chairman of Committees but did not hold any other party, parliamentary or ministerial office.
