Josef Albert Amann (1 July 1866, in Munich – 17 October 1919, in Konstanz) was a German gynecologist.

For several years he worked as an assistant at the university women's clinic in Munich, receiving his habilitation in 1892.

In 1898 he succeeded his father as head of the second gynecological department at the Allgemeine Krankenhaus in Munich.

In 1897 he published Kurzgefasstes Lehrbuch der mikroskopisch-gynäkologischen Diagnostik, an influential textbook of microscopic gynecological diagnostics.
