Jack Lawrence (born 21 March 1897; date of death unknown) was an Australian rugby league footballer who played in the 1910s and 1920s.
He played for South Sydney in the NSWRL competition during which the club won 5 premierships in 11 seasons.
Lawrence would go on to win a premiership with Souths in his debut season as the club finished first on the table and were declared premiers without needing to play in a grand final.
Lawrence played at prop in the match which Souths lost 3-0 which was the lowest scoring grand final at the time.
In 1925, Lawrence was part of the South Sydney side which went the entire season undefeated and won the premiership outright without needing to play in a grand final.
