Captain John W. Wilton was a soldier and politician in Manitoba, Canada.
Wilton lived in Winnipeg, and served with Canadian forces overseas prior to his career in politics.
Wilton served in the Legislative Assembly of Manitoba from 1915 to 1920, as a member of the Liberal Party.
He first ran for the Manitoba legislature in the 1914 provincial election, and finished second against Conservative John Thomas Haig in the Winnipeg-area constituency of Assiniboia.
He ran again in the 1915 campaign, and defeated Labour candidate William Bayley by fifty-five votes (Haig finished third). The Liberals won a landslide victory in this election, and Wilton served as a backbench supporter of Tobias C. Norris's government for the next five years.
He appears to have left the Liberal Party just before the 1920 provincial election: campaigning for re-election as an independent, he lost to William Bayley by 103 seats.
