Wernher von Homberg (also Werner; Hohenberg, 1284 – 21 March 1320) was a knight in the service Emperor Henry VII, and later of Frederick the Fair.
She was patron of the Oetenbach nunnery, and Wernher's sister, Cecilia von Homberg became the prioress there.
Wernher inherited territories that today form the northern part of the canton of Schwyz.
Beginning in 1302, king Albert I of Germany laid claim to these territories, prompting Wernher to enter a pact with the people of Schwyz.
For his service in Milan, he received the title of lieutenant general of Lombardy as well as the right to collect the imperial tax at Flüelen.
