Anna ("Anni") Christine Friesinger-Postma (born 11 January 1977 in Bad Reichenhall) is a former Germanspeed skater. Her father Georg Friesinger, of Germany, and mother Janina ("Jana") Korowicka, of Poland, were both skaters; Jana was on the Polish team at the 1976 Winter Olympics. Her brother Jan is also a speed skater. Her sister Agnes is a 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.
On 11 August 2009 Friesinger married former Dutch skater Ids Postma, her long-term boyfriend, at Schloss Mirabell. The celebration took place at Schloss Aigen. As of November 2013, Friesinger lives in Salzburg, Austria, and is planning to move to the Netherlands to live with Postma on his farm. In August 2011 she gave birth to a daughter. 
Friesinger has won five Olympic medals; gold at the 1500 m in the 2002 Winter Olympics and the team pursuit in the 2006 and 2010 Winter Olympics as well as bronze at the 3000 m in the 1998 Winter Olympics and the 1000 m in the 2006 Winter Olympics. She managed to qualify for the German speed skating team in five events at the 2006 Winter Olympics: the team pursuit and the individual races at 1000 m, 1500 m, 3000 m, and 5000 meters. However, she failed to win gold in any individual events. In the team pursuit semifinal against the United States at the 2010 Olympics, she fell behind her team members and ended up sliding across the finish line on her belly, but Germany still succeeded in advancing to the final.
Friesinger has set the world record at the 1500 m distance three times during her career, but the record has since been superseded by Canadian competitor Cindy Klassen. The Olympic record, however—1:54.02—still belongs to Friesinger, and was set 20 February 2002 during her winning run at the 2002 Winter Olympics in Salt Lake City.
Friesinger has done some modeling work as a sideline, and she has appeared as a swimsuit model in several publications. She is also known for her particularly powerful thighs, as befits a champion speed skater.
