The 2018 GoPro Grand Prix of Sonoma was the 17th and final race of the 2018 IndyCar Series season. The race was held on September 16 at Sonoma Raceway in Sonoma, California. 2014 Indy 500 winner Ryan Hunter-Reay qualified on pole position, and took victory in the 85-lap race. This also marked the last IndyCar Series race at Sonoma, as in 2019, the season finale will be held at the WeatherTech Raceway Laguna Seca. It was also the final race for Verizon Communications as the series sponsor, as NTT took over as title sponsor for 2019.
