Park Hyo Shin (박효신) is a South Korean singer known for his unique vocals and melodic ballads.

Since his debut in 1999, Park Hyo Shin has mesmerized listeners in South Korea with his husky tone, masterful technique, and unmatched vocal control.

Considered by many to be the best singer in Korea, Park Hyo Shin's songs have never failed to place near or at the top of Korea's music charts. PHS had his first #1 ranking track with "좋은 사람" (Good Person) from his third album, a song highlighted by his husky vocals and emotional delivery. With the release of his fourth album, PHS managed to achieve another #1 track with "그 곳에 서서" (Standing in That Place). PHS is also well known for his song, "눈의 꽃" (Snow Flower), a Korean remake of Mika Nakashima's "雪の華" (Yuki no Hana). PHS's version was used as the main theme for the Korean drama, 미안하다 사랑한다 (I'm Sorry, I Love You).

Three years after the release of his fourth album, PHS returned to the music scene with his fifth album and a new vocal style, focusing on a lighter and more relaxed tone. His fifth album was well-received and opened a path for his newfound voice.

PHS has recently had many problems with his current agency, Nawon Entertainment. The label seems to be overworking and under-paying the singer, resulting in a heartfelt confession by PHS during the 2007 Seoul Encore Concert. It is unknown whether PHS will stay with the company for a sixth album.

Even as the years come and go, Park Hyo Shin remains to be one of the top figures in Korean music.
