"Catch Me" (stylized as "Catch Me -If you wanna-" in Japan) is a song by South Korean pop duo TVXQ, also known as Tohoshinki in Japan. Written by Yoo Young-jin and Yoo Han-jin, two versions of "Catch Me" exist: the original Korean-language version, which served as the lead single for the duo's sixth Korean studio album Catch Me (2012), and a Japanese-language version, which was released as the fourth and last single for their sixth Japanese studio album, Time (2013). The Korean version of "Catch Me" was made available for download on September 24, 2012, the same date as the full album's digital release. The Japanese version of "Catch Me" was released by Avex Trax in Japan as TVXQ's 36th Japanese CD single on January 16, 2013.

A mix of house and dubstep, "Catch Me" was met with acclaim, with critics praising the back track's orchestral riffs and the duo's vocal harmony. The song was mildly successful in South Korea, peaking at number sixteen on the Gaon Singles Chart and number twenty-five on the Billboard Korea K-Pop Hot 100. In Japan, "Catch Me" debuted at number one on the Oricon Singles Chart and peaked atop the Billboard Japan Hot 100. Selling over 137,000 copies on its first week of release, "Catch Me" was certified gold by the Recording Industry Association of Japan (RIAJ) for shipments of over 100,000.

Produced by Yoo Young-jin and co-written by Yoo and Yoo Han-jin, "Catch Me" is an electropop song with orchestral melodies, dubstep sounds, house beats, and powerful vocal belting. The lyrics are about a self-respected man who says good-bye to his lover but actually wants to hold onto her. The song was recorded in mid-2012 at the S.M. Blue Ocean Studios in Seoul, South Korea.
