Paul Rostock (18 January 1892 – 17 June 1956) was a Nazi physician, official, and university professor.

From 1927 to 1933, Rostock was assistant medical director at Bergmannsheil Hospital in Bochum and worked with Karl Brandt, who was at that time an intern there.

In 1943, General Commissioner Karl Brandt chose Rostock as his deputy and representative in the Medical Science Research Department.

Because of his very high position, Rostock was charged with complicity in several series of human experiments on concentration camp prisoners.

He then worked as the medical supervisor of Versorgungs Hospital in Bayreuth, from 1953 to his death at age 64 in Bad Tölz.
