The Brethren of the Croatian Dragon (Croatian: Braća hrvatskoga zmaja) is a Croatian historical and cultural society established in 1905.

In 1907, the Brethren claimed to have found the remains of Petar Zrinski and Fran Krsto Frankopan, and by 1919 those were moved to the Zagreb Cathedral. During the Independent State of Croatia, the Brethren was made into a Knight's Order in 1941. The Brethren was restored in 1945 before being banned in Communist Yugoslavia in 1946. It was reestablished in 1990.
