Troy James Hurtubise (born November 23, 1963 in Hamilton, Ontario) is an inventor and conservationist from North Bay, Ontario, Canada noted for his often bizarre creations that he tests on himself. Some of these inventions include the Ursus personal armor suit, firepaste (an ablative heatproofing material), various ray generators, and recently, Trojan, which is a type of body armor.

Hurtubise built a metal suit for protection from grizzly bears; recorded as a National Film Board documentary and called Project Grizzly, in which Hurtubise tested the capabilities of the suit using himself as the test subject. This resulted in his Ig Nobel Prize for Safety Engineering in 1998.
