Euphemia of Kuyavia

Euphemia of Kuyavia (c. 1265 – 18 March 1308^{[citation needed]}) was a Kuyavian princess and Queen consort of Galicia-Volhynia.

She was the daughter of Casimir I of Kuyavia by his third wife Euphrosyne, daughter of Casimir I of Opole. Euphemia was sister of Władysław I the Elbow-high, the wife of Yuri I of Galicia, and the mother of Andrew of Galicia and Lev II of Galicia.

The only preserved evidence of Euphemia's existence is from Jan Długosz's Yearbooks, which reported that Euphemia died on 18 March 1308. She was the daughter of Prince Casimir and the wife of Yuri I, who died in the same year on 21 April, which was also his birthday.^[1]
