Roderick George Toombs (April 17, 1954 – July 31, 2015), better known by his ring name "Rowdy" Roddy Piper, was a Canadian professional wrestler and actor.

In professional wrestling, Piper was best known to international audiences for his work with the World Wrestling Federation (WWF, now WWE) and World Championship Wrestling (WCW) between 1984 and 2000. Although he was Canadian, because of his Scottish heritage he was falsely billed as coming from Glasgow and was known for his signature kilt and bagpipe entrance music. Piper earned the nicknames "Rowdy" and "Hot Rod" by displaying his trademark "Scottish" rage, spontaneity and quick wit. According to The Daily Telegraph, he is "considered by many to be the greatest 'heel' (or villain) wrestler ever.

Outside of wrestling, Piper acted in dozens of films and TV shows, most notably taking the lead role of John Nada in the 1988 cult classic They Live and a recurring role as a deranged professional wrestler called Da' Maniac on the FX comedy series It's Always Sunny in Philadelphia. He was also widely known for his role in Hell Comes to Frogtown as the character Sam Hell.

He played Marlon in the revival series episode "Small Friends".
