Maren Kroymann was born on July 19, 1949, in Walsrode. From 1967 on, she studied British, American, and Romance language and literature in Tubingen. There, she became a part of the feminist movement and started to perform on stage. In 1971, she moved to Berlin and joined among others the politically committed and satirical Hanns-Eisler-Chor. From 1982 to 1986, Kroymann successfully toured Germany with her solo show "Auf du und du mit Stöckelschuh", a satirical, but careful interpretation of 1950s German pop songs. Following this success, Kroymann played leading roles in the TV series "Oh Gott, Herr Pfarrer" (1988-1989) and "Vera Wesskamp" (1992). But despite her success with several other TV series and TV movies, Kroymann always stuck to political satire. She appeared regularly in political satire shows such as "Scheibenwischer" and "Jonas" and even had her own show, "Nachtschwester Kroymann", from 1993 to 1997.

In 1993, Kroymann made her movie debut in the comedy film "Kein Pardon" with Hape Kerkeling. In the following years, Kroymann starred in several other successful comedy movies. But with her leading part in Angelina Maccarone"s award-winning drama "Verfolgt" ("Hounded"), Maren Kroymann finally proves her dramatic talent as a probation officer who engages in an "amour fou" with delinquent (Kostja Ullmann) who is 30 years younger than her.
