Company Sergeant Major John Robert Osborn, VC (2 January 1899 − 19 December 1941) was a Canadian soldier.

Company Sergeant-Major Osborn had to run the gauntlet of heavy rifle and machine gun fire.

With no consideration for his own safety he assisted and directed stragglers to the new Company position exposing himself to heavy enemy fire to cover their retirement.

Shouting a warning to his comrades this gallant Warrant Officer threw himself on the grenade which exploded killing him instantly.

Company Sergeant-Major Osborn was an inspiring example to all throughout the defence which he assisted so magnificently in maintaining against an overwhelming enemy force for over eight and a half hours and in his death he displayed the highest quality of heroism and self-sacrifice.
