Major General Rodney Frederick Leopold Keller CBE (2 October 1900 – 21 June 1954) was a Canadian Army officer who rose to divisional-level command in the Second World War.

Major-General Keller was popular with his troops, who appreciated his manners and outspoken language; however, a drinking problem and several breaches of security measures before D-Day cost him the support of both his superior officers and his own staff.

[3] Ernest Côté, the quartermaster of the 3rd Division, called Keller a "conventional tactician" who was "very much a spit and polish officer who cut quite a figure in his battledress.

[6] Keller's immediate superiors in I British Corps and 2nd British Army considered him unfit to command the division, but Lieutenant General Guy Simonds, who was scheduled to command II Canadian Corps upon its activation in Normandy, held off on making a decision about his relief, even refusing a resignation by Keller who himself admitted to the strain.

"[7] Despite the continued complaints from above and below, Simonds, and Lieutenant General Harry Crerar, another of his admirers and commander of the First Canadian Army, refused to relieve him.
