Carl Posner (16 December 1854 in Berlin – 20 December 1928 in Berlin) was a German urologist.
He studied natural sciences and medicine at several German universities, receiving his PhD at Leipzig in 1875 and his medical doctorate at Giessen in 1880. Afterwards, he settled into a medical practice in Berlin, and in the meantime, received training in urology as a private assistant to Ernst Fürstenheim (1836–1904). In 1889 he obtained his habilitation, and shortly afterwards worked as a lecturer at Friedrich-Wilhelms-Universität in Berlin, where in 1903 he became an associate professor of internal medicine.
He is remembered for his pioneer work involving testicular puncture biopsy in the investigation of infertility in humans, as well as for the eponymous "Posner test", a means used for determining the presence of albumin in urine.
