The Bosnian Church (Serbo-Croatian: Crkva bosanska, Црква босанска) was an autonomous Christian church in medieval Bosnia and Herzegovina.

Historians traditionally connected the church with the Bogomils, although this connection has been challenged, and is now rejected by the majority of scholars. Adherents of the church called themselves simply Krstjani ("Christians") or Dobri Bošnjani ("Good Bosnians"). The church's organization and beliefs are poorly understood, because few if any records were left by church members; the church is mostly known from the writings of outside — primarily Catholic — sources.

The monumental tombstones called stećak that appeared in medieval Bosnia, as well as Croatia, Serbia, and Montenegro, are sometimes identified with the Bosnian Church.
