Kvitova won her first Grand Slam title and fourth tournament of the year with a 6-3, 6-4 victory on the famed grass court.
The eighth-seeded Kvitova used a full arsenal of left-handed ground strokes to win 72 percent of her first serves to Sharapova's 58 percent. Sharapova served three aces, but Kvitova had 19 winners to her 10.
The loss dropped Sharapova to 3-2 in Grand Slam finals. She won Wimbledon in 2004.
