Georges Friedel (19 July 1865 in Mulhouse – 11 December 1933 in Strasbourg) was a French mineralogist and crystallographer.

Georges was the son of the famous chemist Charles Friedel. Georges' grandfather was Louis Georges Duvernoy who held the chair in comparative anatomy from 1850 to 1855 at the Muséum national d'histoire naturelle.

Georges studied at the École Polytechnique in Paris and the École Nationale des Mines in St. Etienne, and was a student of François Ernest Mallard. In 1893 he obtained a professorship at the École Nationale des Mines, the director of which he would later become. After the First World War, he returned as a professor at the University of Strasbourg in Alsace. Due to ill health, he took early retirement in 1930, and died in 1933. He was married with five children.

Like his teacher Mallard, Friedel concerned himself with the theories of Auguste Bravais, the founder of crystallography. Friedel was able to demonstrate the theoretical ideas of Bravais (the Bravais lattice) with the help of x-ray diffraction experiments on crystals, and so provide the physical basis therefore. One of his most important discoveries was the law that now bears his name.

In 1897, Georges Friedel synthesised and identified calcium chloroaluminate which received his name. Georges Friedel also synthesised calcium aluminate in 1903 in the framework of his work on the macles theory.
