Gustav, also known as Gustavus, (Hungarian Gusztáv, 1966-1979) was a Hungarian series of animated short cartoons (5 minutes) for adults.

Each episode tells an adventure of the main character, Gustav, related to the grey realities of urban life. Characteristic feature of the show was that episodes were independent: for example, Gustav is sometimes a bachelor, sometimes has large family.

In Eastern Europe and Yugoslavia the episodes were broadcast on TV in the 80s, usually as airtime filler. The series was also broadcast in Western Europe and even in New Zealand - because it was not using language, other than gibberish sound, it was able to easily transcend boundaries. In 2013 and 2014, Gusztáv was again broadcast in Croatia, on national television, usually as an airtime filler. However, over 40 episodes were broadcast between films in special Christmas/New Year film marathons.
