The Circle K/Fiesta Bowl 200 was the final name of a PPG IndyCar World Series race held annually at Phoenix International Raceway in Avondale, Arizona, from 1979 though 1986; it was known as the Miller High Life 150 for five editions during that period.

The race was known by multiple other names, operated under other sanctioning bodies, and was run at other distances during a much longer history before IndyCar.

Open wheel racing in the Phoenix area dates back to 1915 on a dirt oval at the Arizona State Fairgrounds.

Earl Cooper, who competed in the Indianapolis 500 seven times, won the inaugural race—scheduled for 150 laps of the one-mile track, it was ended after 109 miles due to darkness.

[5] Bobby Ball naming returned for the 1976–1978 editions, the last of which was title sponsored by Miller High Life.
