Philipp Phoebus (23 May 1804, Märkisch-Friedland in West Prussia – 1 July 1880, Gießen) was a German physician and pharmacologist.

Afterwards he continued his education in Würzburg with Johann Lukas Schönlein (1793-1864) and Karl Friedrich Heusinger (1792-1883), in Paris under Pierre Charles Alexandre Louis (1787-1872) and at Strasbourg, where he focused on anatomical studies.

Following travels in Switzerland and northern Italy, he returned to Berlin, where in 1832 he became privat-docent for normal and pathological anatomy.

In 1843 he was appointed chair of pharmacology at the University of Giessen, a position he held until health reasons forced an early retirement in 1865.

He was an advocate for the training and employment of female pharmacy assistants, and believed in an academic qualification of pharmacists.
