The CRC Churches International is a Pentecostal Protestant Christian denomination located primarily in Australasia.

The CRC Churches International was founded (as the National Revival Crusade) in 1945 at Adelaide, South Australia by Pastor Leo Cecil Harris (1920-1977). In 1952, it became known as the Commonwealth Revival Crusade, until 1963 when it became the Christian Revival Crusade. The name CRC Churches International was adopted in 1998 in light of its international growth, especially in Papua New Guinea.

As of 2005, they have approximately 100,000 members worldwide, with 129 churches in Australia and around 400 churches worldwide. Its biggest international branch is Papua New Guinea with around 200 churches.

They hold to a conservative Protestant theology, as well as to the core Pentecostal doctrines such as the Baptism of the Holy Spirit, speaking in tongues, and faith healing.
