Bocicoiu Mare (Hungarian: Nagybocskó or Újbocskó, Ukrainian: Великий Бичків, romanized: Velykyi Bychkiv, Yiddish: ביטשקוב, romanized: Bitshkif or Bicskof) is a commune in Maramureș County, Maramureș, Romania.

It lies 9 kilometres east of Sighetu Marmației, across the Tisza River from Velykyy Bychkiv, Ukraine.

After the failed revolution led by Francis II Rákóczi, Germans settled down in the area.

After World War I, the village was split in two, and the river became a natural border of the two countries, with Velykyy Bychkiv in Czechoslovakia.

At the 2002 census, 76.8% were Romanian Orthodox, 8.5% Roman Catholic, 8.2% Greek-Catholic, and 4.7% stated they belonged to another religion.
