Slam Dunk (stylized in all caps) is a Japanese sports manga series written and illustrated by Takehiko Inoue. It was serialized in Shueisha’s shōnen manga magazine Weekly Shōnen Jump from October 1990 to June 1996, with the chapters collected into 31 tankōbon volumes. The story follows a basketball team from Shōhoku High School, located in the Shōnan area of Japan.

Hanamichi Sakuragi, a delinquent outcast and leader of a gang – who was rejected fifty times – encounters Haruko Akagi, who recognizes Hanamichi’s athleticism and introduces him to the Shohoku basketball team. Hanamichi was reluctant to join the team at first as he had no previous sports background (and because the fiftieth girl rejected him for a basketball player), but despite his immaturity and hot temper, he proves to be a natural athlete with potential, initially joining the team in order to impress Haruko, but later coming to love the sport and working his best to help the team win the nationals.

The manga was adapted into an anime television series by Toei Animation which aired from October 1993 to March 1996. The series has been broadcast worldwide, gaining popularity especially in Japan, Europe, and several other Asian countries. In December 2022, an anime feature film titled The First Slam Dunk was released in Japan. Slam Dunk has 185 million copies in circulation, making it one of the best-selling manga series in history.

In 1994, it received the 40th Shogakukan Manga Award for the shōnen category. In Japan, Slam Dunk has been regarded as one of the greatest sports manga series of all time and has been cited as a contributor in popularizing basketball among Japanese youth during the 1990s. In 2010, Inoue received special commendations from the Japan Basketball Association for helping popularize basketball in Japan.
