Saxonburg is a borough (comparable to a town) in Butler County, Pennsylvania in the United States. It is part of the Pittsburgh metropolitan area in the western part of the state. It was founded in 1832 by F. Carl Roebling and his younger brother John A. Roebling as a German farming colony. The population of Saxonburg was 1,525 as of the 2010 census.
The city was first named "Germania" and "Sachsenburg" before its name was anglicized to the present one. After Roebling returned to his engineering career, he developed his innovation of wire rope in a workshop here. He became known for his design of suspension bridges, including the most famous one, the Brooklyn Bridge in New York.

This was changed to "Sachsenburg" and later anglicized to Saxonburg. Roebling had emigrated with his brother Carl and a group of pioneers from Prussia (Germany) in 1831 to flee political unrest and oppression. The two men, along with a handful of a larger group who accompanied them on the trans-Atlantic journey, bought 1,582 acres (6.40 km2) of land on October 28, 1831, from Mrs.
