James Warren "Jimmy" White MBE (born 2 May 1962) is an English professional snooker player. Nicknamed "The Whirlwind" and popularly referred to as the "People's Champion", White is a multiple World Championship finalist renowned for losing each of the six finals he contested.

White's extensive list of achievements, however, also include victory in the World Amateur Championship, the UK Championship and the Masters. He is also a former World Doubles champion with Alex Higgins, won the World Cup twice and Nations Cup once with England and was the 2010 World Seniors Champion. In 1992, he became the first left-handed player, and second overall, to record a maximum break at the World Championship.

White was born in Tooting, London, England, and studied at Ernest Bevin College. He never achieved academic success, as he was often truant from school from the age of eight or nine, spending more and more time at Ted Zanicelli's snooker hall. It was around this time that he met Tony Meo with whom he would compete in money matches in many venues. His natural aptitude for snooker led to a successful amateur career. After winning the English Amateur Championship in 1979, a year later he became the youngest-ever winner of the World Amateur Snooker Championship, aged 18.
