Kirsi Hannele Viilonen (born 26 October 1964 in Tampere — died 3 December 2005 in Nokia), better known by her stage name Kikka, was a Finnish pop/schlager singer. She was known for her sexpot image and suggestive, equivocal songs. Her career was launched in the late 1980s, inspired by the success of such busty international stars as Samantha Fox and Italy's Sabrina Salerno. Kikka's best-known songs were "Mä haluun viihdyttää" ("I Want to Entertain"), "Sukkula Venukseen" ("A Shuttle to Venus"), "Tartu tiukasti hanuriin" ("Grab the Accordion Firmly" in slang the word hanuri often refers to butt) and cover of Ami Aspelund's Apinamies ("Apeman").

The peak of Kikka's popularity was in the late 1980s and early 1990s when she earned three platinum records and two gold records.
