Park Hyo-shin (Korean: 박효신; born September 1, 1981) is a South Korean singer and musical theatre actor. Following his debut as a singer in 1999, Park released numerous hit songs in the 2000s, including "Good Person" (2002), "Snow Flower" (2004) and "Memories Resemble Love" (2007). In the 2010s, he achieved five number-one hits on the Circle Digital Chart, including 2014's "Wild Flower", which has sold 5 million copies, making it one of the best-selling singles in South Korea.

Park Hyo-shin was born on September 1, 1981, in South Chungcheong Province, South Korea. He discovered his love of singing as a child from singing trot music at his family's restaurant. In high school, Park won prizes at several competitive singing festivals, including the grand prize at the Bucheon Youth Song Festival.

After graduating high school, Park trained to be a singer for over a year. In January 2000, he released his first album, Things I Can't Do For You (해줄 수 없는 일), which includes the lead single of the same name and the follow-up hit single "Fool" (바보). The album sold more than 446,000 copies by the end of the year and garnered Park a win for Best New Artist at the 2000 Golden Disc Awards. That year, Park made his musical theatre debut in the lead role of Rock Hamlet, which premiered in April 2000 at Seoul's Jangchung Gymnasium.

In January 2001, Park released his second album, Second Story, and its lead single, "Far Away" (먼곳에서).

He released his third album,Time Honored Voice, in September 2002. The album's lead single, "Good Person" (좋은 사람), was number one for four weeks on South Korea's Music Box Chart. For the song, Park won bonsang awards at a slew of year-end award shows, including the Golden Disc Awards and Seoul Music Awards.

Park released his fourth album, Soul Tree, in April 2004. The album topped the Recording Industry Association of Korea's monthly album chart, while the lead single, "Standing There" (그 곳에 서서), ranked number one for three weeks on the Music Box Chart. That November, Park released "Snow Flower" (눈의 꽃), a song for the original soundtrack of the television show I'm Sorry, I Love You. The song, which is a cover of "Yuki no Hana" by Japanese singer Mika Nakashima, was a hit for Park and also reportedly gave a boost to Nakashima's album sales in South Korea.

In June 2005, Park released Neo Classicism, a remake album of hit Korean songs from the 1980s and 1990s. He followed this up with the release of his fifth studio album, The Breeze of Sea, in January 2007. The album's lead single, "Memories Resembles Love" (추억은 사랑을 닮아), debuted in the top ten of weekly South Korean digital song charts and remained at the top of the charts for several months.

He not only participated in his album but was also a singer for many original soundtracks inserted in TV programs and movies. Park sang "Hwashin," or "Flower Letter", for the original soundtrack of the 2008 SBS period drama Iljimae. In 2008, he also participated in Hwang Project as the lead vocal by releasing the song "The Castle of Zoltar," which was quite different from the music that he sang in early stage of his career.^{[citation needed]}
