Caddyshack is a 1980 US comedy film directed by Harold Ramis and written by Brian Doyle-Murray and Ramis. It stars Chevy Chase, Rodney Dangerfield, Ted Knight, Michael O'Keefe and Bill Murray. It is Ramis's first feature film and was a major boost to the career of Dangerfield. Grossing almost $40 million in the US alone (16th highest of the year) it was the first of a series of similar comedies.

Set on Bushwood Country club golf course it is a broad clash between classes, on one side privilege, manners and rules on the other anarchic, young and noisy. The club is represented by Judge Smails (Knight) and opposite him vulgar, noisy, witty Al Czervik (Dangerfield) and a group of caddies including Danny Noonan (O'Keefe). Ty Webb (Chase) is a rich golf expert who plays both sides and Carl Spackler (Murray) is a lunatic groundman locked in struggle with a gopher. The plot hinges on two key golf matches, in the first of which Noonan wins a scolarship and the favour of Smails. The second is an illegal high stakes gambling match which forces Danny to side either with Czervic or Smails, at the end of which Spackler dynamites the majority of the course trying to kill the gopher.

Caddyshack shares a similar feel to Animal House (1978), also written by Ramis and produced a belated sequel in 1988, Caddyshack II.
