La Coppa del mondo di mountain bike 1999 organizzata dall’Unione Ciclistica Internazionale (UCI) e supportata da Diesel si è disputata in tre discipline: cross country, downhill e dual slalom, con otto tappe per ogni disciplina.
Una coppa del mondo in mano ai francesi, come negli ultimi 6-7 anni, dove Vouilloz e la Chausson hanno dominato lasciando agli avversari solo qualche vittoria di tappa.
