Ken Butler III (born May 2, 1982) is an American professional stock car racing driver.

[6] Butler ran a limited schedule in the 2007 ARCA Re/Max Series with Eddie Sharp Racing as part of its driver development program.

[8] However, a damper was put on Bulter's win as he bumped Michael McDowell out of the way in what some, including Schrader, called an unfair move.

[9] Continuing to run as part of ESR and Michael Waltrip Racing's development program, he ran along teammates Justin Lofton and Scott Speed.

[13] Two years later, Butler signed with R3 Motorsports to run just about half the schedule in the Nationwide Series and named Aaron's as sponsor.
