A slam dunk, also dunk or dunk shot, is a type of basketball shot that is performed when a player jumps in the air, controls the ball(s) above the horizontal plane of the rim, and scores by putting the ball directly through the basket with one or both hands. This is considered a normal field goal attempt; if successful it is worth two points. Such a shot was known as a "dunk shot" until the term "slam dunk" was coined by former Los Angeles Lakers announcer Chick Hearn.

is a sports-themed manga series written and illustrated by Takehiko Inoue about a basketball team from Shohoku High School. It was serialized in Weekly Shonen Jump from 1990 to 1996, with the chapters collected into 31 tankobon volumes by Shueisha. It was adapted into an anime series by Toei Animation which has been broadcast worldwide, enjoying much popularity particularly in Japan, several other Asian countries and Europe. As of 2012, Slam Dunk had sold 120 million copies in Japan alone, making it one of the best-selling manga series in history. Inoue later used basketball as a central theme in two subsequent manga titles: Buzzer Beater and Real. In 2010, Inoue received special commendations from the Japan Basketball Association for helping popularize basketball in Japan.

In mathematics, particularly low-dimensional topology, the slam-dunk is a particular modification of a given surgery diagram in the 3-sphere for a 3-manifold. The name, but not the move, is due to Tim Cochran. Let K be a component of the link in the diagram and J be a component that circles K as a meridian. Suppose K has integer coefficient n and J has coefficient a rational number r. Then we can obtain a new diagram by deleting J and changing the coefficient of K to n-1/r. This is the slam-dunk.
