Zenmaro Toki (土岐 善麿 Toki Zenmaro; June 8, 1885 – April 15, 1980) was a Japanese Naturalist tanka poet. After initially taking up tanka in his teens, he studied under Kun'en Kaneko, and when in attendance at Waseda University he socialized with other notable Naturalist poets such as Bokusui Wakayama. Later, he earned the respect of the famous poet Takuboku Ishikawa, with whom he corresponded until the latter's death in 1912.
