A slam dunk, also simply known as dunk, is a type of basketball shot that is performed when a player jumps in the air, controls the ball above the horizontal plane of the rim, and scores by shoving the ball directly through the basket with one or both hands.^[1] It is a type of field goal that is worth two points. Such a shot was known as a "dunk shot"^[1] until the term "slam dunk" was coined by former Los Angeles Lakers announcer Chick Hearn.^[2]

The slam dunk is usually the highest percentage shot^[3] and a crowd-pleaser. Thus, the maneuver is often taken from the basketball game and showcased in slam dunk contests such as the NBA Slam Dunk Contest held during the annual NBA All-Star Weekend. The first incarnation of the NBA Slam Dunk Contest was held during the half-time of the 1976 ABA All-Star Game.

A study was carried out in 2015 to show the effectiveness of different shot types, including slam dunks. The study was carried out across five different levels of basketball (NBA, EuroBasket, the Slovenian 1st Division, and two minor leagues). Overall the study showed that slam dunks were a very effective way of scoring in the game of basketball, particularly in the NBA, which had the highest dunk percentage in the study.^[4]
