Jorge Beauchef (1787 in Le Puy-en-Velay, France – June 10, 1840 in Santiago, Chile) was a French military who participated in the Napoleonic Wars.

He was governor of Lima (to a lesser extent, he participated in the Peruvian War of Independence by commanding an expedition to help José de San Martín, a national hero of Argentina and Peru).

The main buildings of the Faculty of Physical and Mathematical Sciences of the University of Chile are located there and are called "Campus Beauchef".

When he arrived he soon begun to participate in engagement with the royalist; first in the siege of Talcahuano (1817) and later on in the decisive patriot victory at the Battle of Maipú (1818).

In February 1820 he led an amphibious assault on the heavily fortified Corral Bay leading to the capture of Valdivia.

The royalist forces of Valdivia had fled to Osorno and then gathered at Carelmapu fort where they received orders from Antonio de Quintanilla to confront Beauchef.
