Rokujō Arifusa (1251 - 19 July 1319; 六条 有房) was Minister of the Interior of Japan in the apex of his career.
Rokujō Arifusa was born into the Rokujō clan, a branch of the Minamoto clan, as the son of Rokujō Michiari, who was the son of Koga Michiteru. He thus may be called Minamoto Arifusa in old texts.
His tenure as Minister of the Interior lasted part of 1319; in that title, he was preceded by Ichijō Uchitsune and succeeded by Nakain Michishige.
