Ulrich of Richenthal (died c. 1438) was a chronicler of the Council of Constance (Konstanz).
During the session of the Ecumenical Council of Constance, Ulrich frequented the events and the celebrations in his native town. He met priests, papal delegates and was employed by princes who were present in the city during the council. He wrote in the German dialect of Konstanz an exact and careful account of all, introducing much statistical matter. The original manuscripts contain coats-of-arms as the one in this fragment as well as other historically valuable illustrations.
