Gato Fedorento (pronounced [ˈɡatu fɨðuˈɾẽtu]; "Smelly Cat") is a Portuguese surreal comedy group, known for their subjective and absurd satire centering both on the Portuguese language and the Portuguese social reality. The group is composed of the four comedians José Diogo Quintela, Miguel Góis, Ricardo Araújo Pereira and Tiago Dores. They started their comedy careers as screenwriters, writing for other comedians, which later developed into their own television shows, radio programs, a talk show and several advertising campaigns. They have been credited with introducing and popularizing the surreal humour genre in Portugal and are one of the most important influences in the modern Portuguese comedy. Their humour is heavily influenced by Monty Python.Gato Fedorento, their homonym television show, ran for nine seasons. In its original unique surreal humour, the group is known for overusing Portuguese idioms, especially in indirect speech, within current discourse on their sketches, turning apparently objective quotidian situations into subjective and often illogical ones. Season names during the first four seasons were meant to satirically represent typical Portuguese surnames and are used as a last name for every single character in every episode of the show within their respective seasons. They also use satirical fictional city names that sound like realistic traditional Portuguese villages, often by including altered forms of Portuguese slang, in the same fashion as in the case of the surnames that give the name to the different seasons.

Currently, they have an exclusivity advertisement agreement with Portugal Telecom of unspecified duration, that spans multiple mediums, being the brand ambassadors.
