Jiyai Shin (Hangul: 신지애; born 28 April 1988), also known as Ji-Yai Shin 申智愛, is a South Korean professional golfer currently playing on the LPGA Tour and the LPGA of Korea Tour (KLPGA). She has broken all existing KLPGA records, winning 10 events in 19 starts on the KLPGA Tour in 2007.

In 2005, while she was still in high school, Shin was the only amateur to win a KLPGA event that season when she won the SK Enclean Invitational. She turned professional at the end of the 2005 season.
Returning to the KLPGA as a rookie in 2006, she started her year with a pair of third place finishes in her first two events and went on to claim three wins on the season.
