Fritz the Cat is a 1972 American independent adult animated black comedy film written and directed by Ralph Bakshi in his feature film debut. Based on the comic strip by R. Crumb and starring Skip Hinnant, the film focuses on Fritz (Hinnant), a glib, womanizing and fraudulent cat in an anthropomorphic animal version of New York City during the mid-to-late 1960s. Fritz decides on a whim to drop out of college, interacts with inner city African American crows, unintentionally starts a race riot, and becomes a leftist revolutionary. The film is a satire focusing on American college life of the era, race relations, and the free love movement, and serves as a criticism of the countercultural political revolution and dishonest political activists.

The film had a troubled production history, as Crumb, who is a leftist, had disagreements with the filmmakers over the film's political content, which he saw as being critical of the political left. Produced on a budget of $700,000, the film was intended by Bakshi to broaden the animation market. At that time, animation was seen predominantly as a children's medium. Bakshi envisioned animation as a medium that could tell more dramatic or satirical storylines with larger scopes, dealing with more mature and diverse themes that would resonate with adults. Bakshi also wanted to establish an independent alternative to the films produced by Walt Disney Animation Studios, which dominated the animation market due to a lack of independent competition.

The film's depiction of profanity, sex and drug use, particularly cannabis, provoked criticism from more conservative members of the animation industry, who accused Bakshi of attempting to produce a pornographic animated film, as the concept of adult animation was not widely understood at the time. The Motion Picture Association of America gave the film an X rating (a recent equivalent to NC-17 rating films), making it the first American animated film to receive the rating, which was then predominantly associated with more arthouse films.

The film was highly successful, grossing over $90 million worldwide, making it one of the most successful independent films of all time. It earned significant critical acclaim in the 1970s, for its satire, social commentary and animations, although it also attracted some negative response accusing it of racial stereotyping and having an unfocused plot, and criticizing its depiction of graphic violence, profanity, sex and drug use in the context of an animated film. The film's use of satire and mature themes is seen as paving the way for future animated works for adults, including The Simpsons, South Park, Beavis and Butt-Head, and Family Guy.

A sequel, The Nine Lives of Fritz the Cat (1974), was produced without Crumb's or Bakshi's involvement.
