The Croatian Revolutionary Brotherhood (CRB) (Croatian: Hrvatsko revolucionarno bratstvo (HRB)) was a far right-wing organisation formed in Australia in the early 1960s. The organisation was created by Croatian migrants to Australia from Yugoslavia after World War II. The organisation carried out more than 120 actions in Europe and Australia. As opposed to the Croatian Liberation Movement, an organization founded by Poglavnik Ante Pavelić, CRB was more radical organization and didn't expected any help from Western countries as CLM did.
The organisation was active throughout the territories of Yugoslavia in the early and mid 1960s. Its aim was to start an uprising in Yugoslavia and to establish an independent Croatia. This mission failed due to the intervention of the UDBA, the Yugoslav secret police.

Some CRB members were:Andrić Brothers
These people were also members of Ante Pavelić's Croatian Liberation Movement (HOP) but they left that organisation because they decided they would not achieve their goals through the political route.
The CRB/HRB's motto was: "Život za Hrvatsku". English translation: "Life for Croatia"
