Ai Miyazato (born 19 June 1985) is a Japanese professional golfer who competes on both the U.S.-based LPGA Tour and the LPGA of Japan Tour (JLPGA). Born in Higashi, Okinawa, she started playing golf at the age of 4. As an amateur, she won a professional event on the 2003 LPGA of Japan Tour – the Dunlop Ladies Open in Miyagi Prefecture. She was the top-ranked golfer in the Women's World Golf Rankings on three occasions in 2010. In 2011, Miyazato won the Order of Merit on the Ladies European Tour (LET), despite only playing in two events on that tour, the co-sponsored events with the LPGA. In April 2012, Miyazato won her eighth LPGA event at the inaugural LPGA Lotte Championship in Hawaii, four strokes ahead of runners-up Azahara Muñoz and Meena Lee.

Miyazato credits her father and coach Masaru Miyazato as the individuals most influential to her golfing career.
