Svjetsko prvenstvo u motociklizmu u klasi 500cc za 1999. godinu je osvojio španjolski vozač Àlex Crivillé na motociklu Honda NSR500 u momčadi Repsol Honda Team. Sezona je obilježena ozljedom aktualnog peterostrukog prvaka Michaela Doohana, koji se ozlijedio na trećoj utrci prvenstva, te se potom povukao iz utrkivanja.
Raspored utrka i osvajači postolja 1999. godine je bilo na rasporedu 16 trkačih vikenda Svjetskog prvenstva i na svima su vožene utrke u klasi 500cc.
