Albert I, Count of Werdenberg-Heiligenberg

Albert I, Count of Werdenberg-Heiligenberg (died c. 1365), was the youngest son of Count Hugo II and Euphemia of Ortenburg. He was named by Emperor Louis the Bavarian imperial bailiff around Lake Constance and over Uri, Schwyz and Unterwalden.

In 1344 and 1347 advocacies over the future Appenzell, the neighbourhood of Saint Gall Abbey and the Rhine Valley were pledged to him. After feuds with Austria in 1355 and Montfort-Feldkirch in 1360, the latter settled through his son Albert II's coup on Lake Constance, he died around 1365.
