Bruce Jun Fan Lee (李振藩, 李小龍; pinyin: Lǐ Zhènfān, Lǐ Xiăolóng; 27 November 1940 – 20 July 1973) was an American-born Chinese Hong Kong martial artist, philosopher, instructor, martial arts actor, film director, screenwriter, and the founder of the Jeet Kune Do concept. He is considered by many as the most influential martial artist of the 20th century, and a cultural icon. He was also the father of actor Brandon Lee and of actress Shannon Lee. His younger brother Robert was a musician and member of a popular Hong Kong beat band called The Thunderbirds and was something of a heartthrob in Hong Kong in the 1960s.

Lee was born in San Francisco, California, and raised in Hong Kong until his late teens. His Hong Kong and Hollywood-produced films elevated the traditional Hong Kong martial arts film to a new level of popularity and acclaim, and sparked the second major surge of interest in Chinese martial arts in the West. The direction and tone of his films changed and influenced martial arts and martial arts films in Hong Kong and the rest of the world as well. He is mainly noted for his roles in five feature length films, Lo Wei's The Big Boss (1971) and Fist of Fury (1972); Way of the Dragon (1972), directed and written by Bruce Lee; Warner Brothers' Enter the Dragon (1973), directed by Robert Clouse, and The Game of Death (1978).

Lee became a very iconic figure, particularly among the Chinese, as he portrayed Chinese national pride and Chinese nationalism in his movies. He primarily practiced Chinese martial arts (Kung Fu as a popular westernized term, or Gung Fu in Lee's own word, or more phonetically corrected Gong Fu), particularly Wing Chun.
