The Ukrainian Catholic Eparchy of Chełm–Bełz (or Chełm–Bełz of the Ukrainians ) was an eparchy of first the Ruthenian Uniate Church and later the Ukrainian Greek Catholic Church within the Catholic Church, with territory in part of Poland from 1596 till 1875. Its cathedral, the now Latin Basilica of the Birth of the Virgin Mary, is still found in the former episcopal see of Chełm. It was forcibly suppressed in favor of Eastern Orthodoxy by the Russian Empire in May 1875 in the Conversion of Chełm Eparchy.
