Marika (born Marta Kosakowska on 14 December 1980) is a Polish vocalist, songwriter and radio DJ.

Currently performing avant-pop, she was previously known for her Caribbean-inspired repertoire which incorporated reggae, dancehall, as well as funk and soul music.

[6] In 2007, Marika released her debut solo single, "Moje serce" ("My Heart"), through Karrot Kommando.

In September 2009, Marika started another radio show, Towary kolonialne, on Roxy FM.

In May 2013, she released Chilli Zet Live Sessions, an album consisting of acoustic versions of songs from her previous CDs.

On her next album, titled simply Marta Kosakowska, the singer shifted from reggae and dancehall towards electronic avant-pop.

[13] Released in October 2015, the album was preceded by the singles "Tabletki" and "A jeśli to ja", and was accompanied by Marika's radical change of image.

Marika focused on family life, but continued to perform regularly, and returned with the single "Jak na moje oko" in May 2020.
