The 2015 Chevrolet Dual in Detroit was the first and only doubleheader of the 2015 IndyCar Series season, hosting Rounds 7 and 8 of the 2015 IndyCar Series season. It marked the eighth Detroit Belle Isle Grand Prix since the Verizon IndyCar Series made its debut at the Belle Isle racetrack in 2007 and the third time it held a "dual" two-race IndyCar contest over two days.
Initial practice and then qualifications were held on Friday May 29, 2015. The pole position for the first race was won by Will Power for Team Penske. Race day practice occurred in the morning on Saturday May 30 and Race 1 took place in the afternoon with Carlos Muñoz winning Race 1 of the dual after it was called after lap 47 of a scheduled 70 laps due to rain and electrical storms. His Andretti Autosport teammate Marco Andretti took second, and third place went to Simon Pagenaud of Team Penske.
Qualifying for Race 2 was only partially completed on Sunday May 31 when it was canceled due to heavy rains causing too much standing water on the track. As a result, starting positions were determined by overall point standings. The rain tapered off later in the after race took place later in the day as scheduled. Sébastien Bourdais of KV Racing Technology won a timed-Race 2 which went 68 laps out of a scheduled 70. Takuma Sato racing for A. J. Foyt Enterprises and Graham Rahal of Rahal Letterman Lanigan Racing taking the third podium spot.
