J-Walk () is a South Korean musical duo formed by two Sechs Kies members. As of 2016, they are under YG Entertainment after reuniting with their group Sechs Kies under the label.
After Sechskies had disbanded in 2000, 2 years later, Kim Jae-duck and Jang Su-won formed a duet under Kiss Entertainment, releasing two albums in 2002. Their debut hit Suddenly was very popular among fans, and it went as high as No. 2 on the music charts. However, their follow up album "Someday" was not as successful. They won SBS Gayo Daejeon Popularity Award with former Sechs Kies member Kang Sung-hoon in 2002.
There were talks of releasing a third album for J-Walk. In 2007, they signed with Vitamin Entertainment and released first mini album Sun Shower (ì“°ë¹Â) after a five-year hiatus. They held a showcase of its new album in Seoul in October 2007. Eun Ji-won and Lee Jai-jin joined it onstage to congratulate their comeback.
In June 2008, J-Walk collaborated with their former Sechskies leader Eun Ji-won for a new song called "My Love" in the third album. Since Kim Jae-duck entered the military shortly after, Jang Su-won had to promote the album by himself. Jang Su-won entered the military in December 2009 and he was released from the army in October 2011.
After they were discharged from army, J-Walk has signed under A&G Modes and released some digital songs. They returned with mini album Love...Painfully with main track "Strive" in December 2013. During preparing for a new album comeback, they made the difficult decision to adjust their schedule to join past label DSP Media's first family concert DSP Festival with Eun Ji-won on December 14.
In October 2019, YG Entertainment released the duo autumn photo album.
