Tunnel Rat is a fictional character from the G.I. Joe: A Real American Hero toyline, comic books and animated series. He is the G.I. Joe Team's Explosive Ordnance Disposal specialist and debuted in 1987.

His real name is Nicky Lee, and his rank is that of sergeant E-5. Tunnel Rat is a Trinidadian Chinese who lived in Brooklyn, New York prior to joining the US Army. He graduated from the Army Ranger School at Fort Benning and served time in Grenada. Tunnel Rat specializes in explosive ordnance disposal, and is familiar with most NATO and Warsaw Pact explosive devices and small arms.

The character's facial appearance is based on G.I. Joe comic book writer Larry Hama.

Tunnel Rat made his Marvel Comics series debut in Issue #59 (May 1987) of G.I. Joe: A Real American Hero, in which he was assigned for security to Thunder, Clutch, and Grand Slam. The entire team had been out for some time testing equipment. Tunnel Rat teaches Grand Slam all about the Joe credit cards, as the latter had been having problems with receiving his pay. The group joins up with Dusty, Crankcase, Hawk, Cross-Country, and Outback to take the equipment to Fort Carson, but Tunnel Rat's new payment method gets them attacked by Cobra forces. The Crimson Guardsman Fred VII, Raptor, and Cobra Commander track down the Joe convoy via Tunnel Rat's credit records, old intelligence and the abilities of Raptor's birds. Cobra Commander attacks the entire team in a Pogo Plane. Due to the limited maneuverability of the mountains, the battle is precarious for both sides. Clutch's driving skills saves the day but Cobra Commander escapes with the knowledge that Tunnel Rat has unwittingly given him.

Tunnel Rat has not been a contender in any CBUB matches.
