Thomas Caterer (31 July 1825 – c. 4 January 1917) was a pioneer schoolteacher of Adelaide, South Australia who founded in 1862 a private school for boys which in 1866 became Norwood Grammar School.
His brother, Frederick Isaac Caterer (c. 1840 – c. 24 August 1892), founded a similarly influential school in Glenelg.
His eldest son, T. Ainslie Caterer (died 1923), noted cricketer and teacher, was the first student of the University of Adelaide to be awarded a BA.
