Ulrich I, Lord of Hanau

Ulrich I (c. 1255/1260 – late 1305 or early 1306) was Lord of Hanau from 1281, when he succeeded his father Reinhard I. Through his mother he inherited a sixth share of the wealthy Münzenberg inheritance.

In 1292 his feud with the Archbishop of Mainz ended in defeat and imprisonment at Bingen. A loyal follower of the kings of Germany, he was appointed Landvogt of the Wetterau in 1300, and King Albert granted Hanau its city charter in 1303.
