Colonel James Rowell CB, VD (20 January 1851 – 6 July 1940) was an English-born Australian politician, soldier and horticulturalist.

Born in Cambridge, he migrated to Australia as a child and was educated in state schools.

In 1917, he was appointed to the Australian Senate as a Nationalist Senator for South Australia, filling the casual vacancy caused by the resignation of William Story, who was contesting the House of Representatives.

He contested the 1922 election as a candidate for the Liberal Party, which was a group of disaffected Nationalists opposed to the leadership of Prime Minister Billy Hughes; he was defeated.
