"Bad Boy" is a song recorded by South Korean girl group Red Velvet from their second studio album reissue The Perfect Red Velvet, released by SM Entertainment on January 29, 2018. A hip hop-influenced R&B number, its lyrics were written by JQueenston and Moon Hee-yeon whilst music was handled by The Stereotypes, Maxx Song, Whitney Phillips and Yoo Young-jin.

"Bad Boy" was well received by music critics, who praised its production and the group's "lush contemporary R&B-meets-pop" sound. It was included in Billboard's list of 100 Best Songs of 2018 in addition to topping their ranking of 20 Best K-pop Songs of the year. A commercial success, it became the group's fourth top-two entry on the Gaon Digital Chart and was certified platinum by the Korea Music Content Association (KMCA) for digital sales of over 2,500,000 units. Elsewhere, it peaked at number two on the World Digital Songs chart and number 87 on the Canadian Hot 100.

The song was one of two numbers performed by Red Velvet at the "Spring is Coming" concert in Pyongyang at the East Pyongyang Grand Theatre to an audience that included Kim Jong-un. The concert was seen as an act of cultural diplomacy and intended as part of a wider diplomatic initiative between South Korea and North Korea. Their appearance at the concert made them only the fifth idol group to ever perform in North Korea and the first artist from SM in fifteen years since Shinhwa.
