Benneteau, ranked 41st in the world, fired nine aces and broke the third-seeded Swiss four times in the 80-minute contest.
After sweeping through the first set in 27 minutes, Wawrinka could find no answer. Benneteau broke for a 2-0 lead in the second set and rolled from there.
He finished off the victory with an ace on the first of two match points.
Benneteau next faces either sixth-seeded David Ferrer or fellow Spaniard Tommy Robredo -- who dispatched world number one Novak Djokovic in the third round.
Benneteau is making his ninth appearance in Cincinnati, a key tune-up event for the US Open, the final Grand Slam of the year that starts on August 25.
His previous best showing was a quarter-final in 2009.
He now stands 14-43 against top 10 opponents and 2-2 this season against the elite after beating Toronto Masters champion Jo-Wilfried Tsonga en route to the quarter-finals at Indian Wells.
