S.O.A.P. were a Danish pop music duo made up of the two sisters Heidi "Suriya" Sørensen (born 18 October 1979) and Saseline "Line" Sørensen (born 26 July 1982). Their music was primarily written by Remee and produced by Holger Lagerfeldt for Sony Music Entertainment Denmark. They released two albums before they disbanded in 2002. They are best known for their single "This Is How We Party", and sold almost 2 million albums worldwide.

Their first album Not Like Other Girls won best pop album at the 1999 Danish Music Awards. Remee and Holger Lagerfeldt were also nominated for producer of the year for the album, and "Stand by You" was nominated for best radio hit. In 2017, BuzzFeed listed the song "This Is How We Party" at No. 100 on their list of "The 101 Greatest Dance Songs of the '90s".

S.O.A.P. were described in Billboard as "looking to be the biggest thing out of Denmark since Aqua."
