World Wide Technology Raceway (formerly Gateway International Raceway and Gateway Motorsports Park) is a motorsport racing facility in Madison, Illinois, just east of St. Louis, Missouri, close to the Gateway Arch.

The first major event held at the facility was the CART series on Saturday May 24, 1997, the day before the Indy Racing League's Indianapolis 500. Rather than scheduling a race directly opposite the Indy 500 (as they had done in 1996 with the U.S. 500), CART scheduled Gateway the day before to serve as their Memorial Day weekend open-wheel alternative without direct conflict. For 2000, the race was moved to the fall. In 2001, it was dropped from the CART series schedule, and switched alliances to the Indy Racing League. After mediocre attendance, the event was dropped altogether after 2003. It was later re-added to the schedule for 2017.

The facilities were owned by Dover Motorsports, a group that also owned what is now Memphis International Raceway, along with Dover International Speedway, and the Nashville Superspeedway. After being shuttered on November 3, 2010, it was announced on September 8, 2011 that the facility would be re-opened by St. Louis real estate developer and former Indy Lights driver Curtis Francois and renamed Gateway Motorsports Park.

The 1.25-mile oval is a favorite for many racers due to the unique shape and different degrees of banking in each corner. Turns 1 & 2 have similar characteristics to New Hampshire Motor Speedway while Turns 3 & 4 are similar to Phoenix International Raceway. The track's egg shape mimics the legendary Darlington Raceway and Twin Ring Motegi race tracks.
