Major General William Henry Pferinger Elkins, CB, CBE, DSO (13 June 1883–1964) was a Canadian soldier.

In December 1917, he was evacuated due to illness and convalesced at the Prince of Wales Hospital for Officers at Marylebone, England.

On his subsequent promotion to brigadier general in 1930, he was appointed to command the Royal Military College of Canada, a post he held until 1935.

Royal Military College of Canada aims were to produce officers and engineers, and to provide a general and cultural education.

Consequently, some elementary science work was dropped in favour of advanced studies in imperial geography, military history and economics.

During the construction and industrial growth slump in the Great Depression, engineers found it hard to find employment.

The Elkins piano room at the Royal Artillery (RA) Park Officers Mess in Halifax, Nova Scotia was named in his honour.
