Rollo Gillespie O'Dwyer (23 March 1900 – 17 September 1964) was an Argentine first-class cricketer.
O'Dwyer was born at Gualesquay in March 1900 and was educated in England at Rugby School.[1] In March 1919, five months after the end of the First World War, O'Dwyer was commissioned as a second lieutenant in the 5th Reserve Regiment. Later returning to Argentina, he made three appearances in first-class cricket in March 1930 for Argentina against Sir Julien Cahn's personal eleven, which was touring South America.[2] The three-match series was won 1–0 by the tourists, with two matches ending in a draw. Playing as a wicket-keeper, he took 4 catches and made 2 stumpings across the series.[3] O'Dwyer died in hospital at Gral Galarea in Entre Ríos Province in September 1964.[4]
