Anna Margaretha Geiger (1783–1809) was a German pastellist.

Born in Schweinfurt, Geiger was the daughter of painter Conrad Geiger [de], and took lessons with Johann Christoph Fesel [de] as well.

In 1806 she went to Bamberg and Munich, and studied with Johann Christian von Mannlich.

She settled in Munich, but upon her father's death her health began to fail and she soon died.
