Takatsukasa Tadafuyu (鷹司 忠冬, 1509 – 1546), son of Kanesuke, was a court noble (kugyo) of the late Muromachi period. He held a regent position Kampaku from 1542 to 1545. The succession of the household (Takatsukasa family) was halted after his death until Takatsukasa Nobufusa, adopted son of Tadafuyu, continued it.
