"Kiss" (Korean: 입맞춤) is a dance single performed by South Korean idol singer Sandara Park, a visual and member of the girl group 2NE1. The song was used as part of a promotional campaign for Cass Beer. It features the vocals of her co-member, CL of South Korean girl group 2NE1. The song was released as her first official single in South Korea and was later included in the album To Anyone.

After the release of 2NE1's latest single I Don't Care, the group paused promotions in order to release solo material. "Kiss" was written and composed by YG Entertainment's exclusive Korean music producer Teddy Park, who is known as a member of 1TYM and for his work with Big Bang from 2006 up until early 2009. She had worked with him previously on 2NE1's debut eponymous extended play 2NE1. The lyrics of the song describes a woman who merely wants her lover to kiss her but is turned off by his attitude. In 2009, Oriental Brewery announced that it had chosen Sandara Park and actor Lee Minho to be their newest models for their beverage brand Cass 2x, and the song was used as a result.

"Kiss" was used as the background music for a Cass Beer commercial film that she herself starred in alongside actor Lee Minho. On the same day, the song was released as a CD single and made available for digital download on July 9, 2009. "Kiss" was the first solo single released by her group, which was then followed by Park Bom's "You and I", and CL and Minzy's duet "Please Don't Go". Later, the song was included in the group's first full-length album To Anyone, along with the singles released by the other members.
