George M. Wertz (July 19, 1856 – November 19, 1928) was a Republican politician, teacher and publisher from Pennsylvania.

His father, German-Dunkard Jacob Wertz, an ardent Republican and abolitionist, was the great grandson of a 1735 Palatine immigrant and rose to prominence as a farmer.

His daughter Ada Olive Hager (née Wertz) attended Vassar, graduating in 1908.

A member of the Pennsylvania State Senate from 1909 to 1913, he served as the body's President pro tempore from 1911 to 1913.

Wertz later organized and ran the Johnstown Daily Leader from 1911 to 1917, creating Cambria County's first afternoon newspaper.
