Sigismund Albicus (Czech: Zikmund Albík z Uničova) (c.1360 – July 23, 1427) was a Roman Catholic Archbishop of Prague and a Moravian.
Albicus was born at Uničov, Moravia, and entered the University of Prague when quite young, taking his degree in medicine in 1387.
Desiring to pursue the study of civil and canon law with more profit, he went to Italy and received the Doctor's degree in 1404, at Padua.
He was appointed physician-in-chief to Wenceslaus IV, who recommended him as successor to the archdiocese of Prague, on the death of its incumbent in 1409.
Albicus held it only four years, and when he resigned, in 1413, Conrad of Vechta was elected in his place.
