The polar frontal artery (frontopolar artery (FPA)) is a branch of the anterior cerebral artery that extends to the anterior pole of the brain. 

The polar frontal artery is the next cortical branch of the ACA and arises from the A2 segment of the pericallosal artery or the CMA but can share a common trunk with the FOA and Heubner's artery. An FPA, or the common trunk of the FOA and FPA, arising from the A1 segment of the ACA is a rare finding.
