A lacrosse ball is the solid rubber ball that is used, with a lacrosse stick, to play the sport of lacrosse. It is typically white for men's lacrosse (however the PLL uses optic yellow balls for better TV visibility[1][2]), or yellow for women's lacrosse; but the balls are produced in a wide variety of colours.[3][4]

Beginning with the 2014 season, all three governing bodies for lacrosse in the United States (US Lacrosse, NFHS, NCAA) have mandated that only balls meeting the NOCSAE ball standard may be used for competition. Balls must be emblazoned with the words "Meets NOCSAE Standard" in order to be deemed legal for play by game officials.
Starting by June 2016, all lacrosse balls have had to meet the new NOCSAE Standard[7] for use in official NCAA and NFHS play. Canadian official games require CLA approvals.
