Philip Everett Giebler[1] (born March 5, 1979, in Oxnard, California) is an American race car driver.

Giebler was considered a top American prospect with an opportunity to race in Formula One early in his career.

He returned stateside in 2004 running in the Infiniti Pro Series and Toyota Atlantic, capturing a win in his IPS debut at Homestead-Miami Speedway, before being named as one of A1 Grand Prix A1 Team USA's drivers.

Driving for Playa Del Racing, he qualified for the last starting position and was one of two rookie drivers (Milka Duno being the other) to race in the 2007 Indianapolis 500, but crashed and finished 29th.

For 2008, he unsuccessfully attempted to qualify for the Indianapolis 500 with the same team, now known as American Dream Motorsports.
