The House of Homberg (also spelled Honberg, historically Hochinberc, Hochenberg; also Thierstein, Tierstein) was a noble family of medieval Switzerland; they had the title of count from late 11th to early 16th century.
They ruled over much of what is now northwestern Switzerland, including parts of the cantons of Aargau, Bern, Solothurn and Basel-Landschaft.
Hermann's son Friedrich took the title of count of Homberg and built the castle Neu-Homberg in what is now part of the canton of Basel-Country.
One of Friedrich's sons was Wernher von Homberg, one of the minnesingers featured in Codex Manesse.
Count Oswald von Thierstein in 1479 received Hohkönigsburg in the Alsace as fief from emperor Frederick III.
