Margarete Bause (born 19 January 1959) is a German politician of Alliance 90/The Greens.

[6] Bause is active in the area of human rights in China and supportive of the Uyghurs; her constituency, Munich, is home to the majority of Uighurs living in Germany as well as to the headquarters of the World Uyghur Congress.

[10] In 2014, Bause made headlines when — on a visit to China with a delegation from the Bavarian state parliament — she secretly met with dissident artist Ai Weiwei and later released photos of the meeting.

[11] In August 2019, after asking the German government to support sending UN observers to Xinjiang province,[12] Bause was denied entry to China.

[13] The remaining members of the German Bundestag delegation subsequently cancelled their planned China trip.
