The Conversion of Chełm Eparchy was the forced conversion of the Eparchy of Chełm–Belz that took place between January and May 1875. It was the last eparchy of the Ruthenian Uniate Church that remained on the territory of the Russian Empire following the partitions of Poland. The episcopal seat of the eparchy was in the city of Chełm (Kholm) in Congress Poland. Adherents and clergy were forced to join the Russian Orthodox Church.
