Terrance and Phillip are a pair of fictional characters in the animated television series South Park. They are a comedic duo who live in Canada. Terrance (born Terrance Henry Stoot in the "small village" of Toronto) has black hair and wears a red shirt with a "T", while Phillip (Phillip Niles Argyle of Montréal) has blond hair and a blue shirt with a "P". Like virtually all Canadians in South Park, they are geometrically-figured with small beady eyes and Pac Man-like heads which flap up and down whenever they speak. This may originally have signified they were an animated series inside an animated series, but was quickly retconned into a distinguishing feature of Canadians.

In South Park, Terrance and Philip are the stars of a popular children's television show. This show-within-a-show serves an interesting role; the parents of the South Park characters view Terrance and Philip's obsessive fart gags in much the same way that many parents in the real world view South Park: with considerable contempt. The two characters have heavy accents, ostensibly to represent stereotypical American views of Canadians. (The "aboot" pronunciation has also been used in The Simpsons and Canadian Bacon. The fact their career is based on an accidental fart Phillip made on The Ed Sullivan Show at the age of six, because that was the only part of their act Americans understood,[1] may be saying something about Canadian perceptions of Americans.)

The duo popularized a catchphrase in the show-within-a-show, as they would invariably say "You FAH-ted!" and then giggle to almost any farting sound. The initials on their shirts may serve as another hidden joke. The letters P and T when pronounced in French sound like péter, slang for fart. TP is also a well known abbreviation for the words 'toilet paper', which can be heard frequently on the cartoon show Beavis and Butthead where Beavis says "I am Cornholio... I need TP for my bunghole."

Terrance and Phillip are huge celebrities within the South Park universe, and have won the Nobel Peace Prize. In one episode they briefly broke up, but then were reunited.
