Sir Theodore Ouseley Pike KCMG (2 August 1904 – 27 December 1987) was an Irish colonial administrator and a rugby union international.
In his youth, Pike was a keen sportsman: he played rugby union, usually as prop.
He was good enough to play to international standard and represented Ireland, by then a divided nation politically but still fielding an All-Ireland rugby team, for two seasons.
Pike made his career in colonial administration, rising to become from 1954 to 1959 Governor and Commander-in-Chief of British Somaliland, now the unrecognized state of Somaliland, in international law a part of Somalia.
Sir Theodore retired to Guildford in Surrey and died in 1987.
