The Grand Prix of Portland (known as the BitNile.com Grand Prix of Portland for sponsorship reasons) is a race in the IndyCar Series held at the Portland International Raceway in Portland, Oregon. The race was an annual event from 1984 to 2007, initially as a race in the CART series, and later as part of the Champ Car World Series. After a ten-year hiatus, the race made its return to the IndyCar Series in the 2018 season. [1]

Portland is best-remembered as being the site of two of the closest finishes on a road course in Indy car racing history. In 1986, Michael Andretti lost fuel pressure on the final turn of the final lap, which allowed his father Mario to catch up and beat him to the finish line by 0.070 seconds. At the time, it was the closest finish of any race in Indy car history. In 1997, in a three-wide finish, Mark Blundell beat second place Gil de Ferran by 0.027 seconds, and beat third place Raul Boesel by 0.055 seconds. For a road course race, it was the all-time closest finish in CART series history, as well as the closest three-car finish in series history.

For nearly its entire existence, the title sponsor of the race was G.I. Joe's sporting goods and auto parts store, and the event was held during or around the Portland Rose Festival. Numerous times, the race was held on Father's Day. Beginning in 2018, the race was held in September on Labor Day weekend, promoted by Green Savoree Racing Promotions.
