Anna ("Anni") Christine Friesinger-Postma (born 11 January 1977) is a German former speed skater.

In July 2010, Friesinger retired from her active sports career when she had to be treated for severe cartilage damage in her right knee joint.

[1] On 11 August 2009 Friesinger married former Dutch skater Ids Postma, her long-term boyfriend, at Schloss Mirabell.

In this, Friesinger became the fifth skater in history to be a World Champion in both Allround and Sprint disciplines (along with Sylvia Burka, CAN (1976 and 1977); Eric Heiden, U.S. (1977 and 1977); Natalya Petrusyova, URS (1980 and 1982); and Karin Kania-Enke, GDR (1980 and 1982)).
