Hans Kundrat (October 6, 1845 – April 25, 1893) was an Austrian pathologist born in Vienna.
He studied medicine in Vienna, and as a student he was a demonstrator under Josef Hyrtl and Karl von Rokitansky. In 1868 he received his medical doctorate, and remained in Vienna as an assistant to Rokitansky. In 1873 he obtained his habilitation, and in 1877 attained the chair of pathology at the University of Graz. Five years later he returned to the University of Vienna as chair of pathology, a position he kept until his death. One of his better known students was Richard Paltauf (1858–1924).
