Jean Baptiste Philippe Barth (24 September 1806 – 20 November 1877) was a French pathologist who was a native of Sarreguemines.
He studied medicine at the University of Paris, and was afterwards an assistant to Pierre Charles Alexandre Louis (1787-1872) at the Hôpital de la Pitié.
In 1840 he was appointed médecin des hôpitaux, and practiced medicine in Parisian hospitals for the next thirty years.
Jean Barth is remembered for treatises on auscultation that he co-authored with pediatrician Henri-Louis Roger (1809-1891).
