Johann Gaspar Spurzheim (31 December 1776 – 10 November 1832) was a German physician who became one of the chief proponents of phrenology, which was developed c. 1800 by Franz Joseph Gall (1758–1828).

Spurzheim was born near Trier, Germany, on 31 December 1776 and studied medicine at the University of Vienna.

Gall intended to have Spurzheim as his successor and added his name as a co-author to books and publications.

He greatly popularised phrenology, and travelled extensively throughout Europe, achieving considerable success in England and France.
