Mezhyrichchya (Ukrainian: Межи́річчя, Polish Międzyrzecze; until 1940 Parchacz) is a village in Chervonohrad Raion, Lviv Oblast, Ukraine.

Until 1934, it was part of the independent "unit gmina" called Parchacz in the Polish Second Republic.

Afterwards the village belonged to the collective rural gmina with the same name in the powiat of Sokal in the Lwów Voivodeship of which it was the seat.

As a result of the Soviet invasion of Poland as part of the Second World War in September 1939, the eastern border of Poland was moved westward to the Bug and Solokiya Rivers, resulting in the village as well as the rest of the gnima of Parchacz now being located in the USSR.

He was a Polish lawyer, historian, publicist, and nephew of Tadeusz Boy-Żeleński.
