"Jekyll & Hyde" is the fourth digital single by Korean DJ and producer Justin Oh, featuring Hyolyn of SISTAR. It was released internationally on March 10, 2017, and one day later in Korea in a Korean-language version.

This release is Hyolyn's first within the international EDM label Spinnin' Records, on which she got signed in February 2017. The English version of the song features her voice in the chorus (an uncredited singer sings the verses), while she sings on the entirety of its Korean version.

The music video of the song was shot in South Korea, Singapore, Japan and Bali (Indonesia).
