JOOP! is a German fashion and cosmetic brand founded by designer Wolfgang Joop in 1978. The designer used his own name as the basis for the brand, but added the exclamation mark to distinguish it from himself. JOOP! showed its first ready-to-wear collection in 1982 and added menswear to the line in 1985.

Wolfgang Joop left the company in 2001, but the brand has survived. The brand has been owned by Holy Fashion Group, based in Switzerland, since 2008, although Coty has licensed the JOOP! cosmetics and fragrances. JOOP! focuses mainly on the markets in Austria, Switzerland and Germany and is today one of the most popular and recognized brands in Germany.
