In ice hockey, a natural hat trick is a rare feat that occurs when a player scores three consecutive goals in a single game without any other players scoring in between. The term "natural" is used to distinguish it from other types of hat tricks, such as a regular hat trick, which occurs when a player scores three goals in the course of an entire game, but other players may score goals in between that players goals.

The NHL record for the fastest natural hat trick is 21 seconds, set by Bill Mosienko in 1952 for the Chicago Blackhawks. A natural hat trick can occur across multiple periods as long as nobody else scores, but it does not take place if the goal comes from a shootout, as its not considered part of regular play.

In response to a natural hat trick, fans traditionally throw their hats on the ice to celebrate the achievement. Interestingly, different teams and fans have their unique ways of celebrating a hat-trick. For example, fans of the Nashville Predators throw a catfish on the ice, while the Detroit Red Wings will throw an octopus.
