The following is a list of notable Old Alleynians, former pupils of Dulwich College, in south London, England.
Years of birth and death (when listed) are given in full. Years at the college are given last, using two digits if unambiguous. All entries are placed in alphabetical order by surname, paying particular attention to any double-barrelled surnames, in which the letters of the first surname take priority.
Note that the award made to Herbert John Leslie Barefoot (detailed above under 'Military') was made in a military capacity for gallantry that was not in the face of the enemy, hence it is not repeated here.
Seven Old Alleynians have won the Victoria Cross, five in the First World War, 1914–18 (of whom four were killed in action) and two in the Second World War, 1939–45. Also in the Second World War one OA won the George Cross.
