1989–90 USAC Championship Car season
The 1989–90 USAC Gold Crown Championship season consisted of one race, the 74th Indianapolis 500 on May 27, 1990. The USAC National Champion and Indianapolis 500 winner was Arie Luyendyk.
The schedule was based on a split-calendar, beginning in June 1989 and running through May 1990. Since USAC had dropped out of sanctioning Indy car races outside the Indy 500, the Gold Crown Championship consisted of only one event. The preeminent national championship season was instead sanctioned by CART.Final points standings
