Michael Joseph "Roger" Hartigan (12 December 1879 – 7 June 1958) was an Australian cricketer and administrator.
Hartigan became Australia's 92nd Test debutant on 10 January 1908 for the Third Test of the 1907–08 Test series against England. Batting at number eight in the second innings, Hartigan (scoring 116) added 243 runs for the eighth wicket – still an Australian Test cricket record – with Clem Hill (160) in oppressive heat at Adelaide Oval.
Missing the Fourth Test through business commitments, Hartigan returned for the Fifth Test of the 1907/08 season six weeks later in Sydney scoring just 1 and 5.
