Nozawa Bonchō (野沢 凡兆?, 1640–1714) was a Japanese haikai poet. He was born in Kanazawa, and spent most of his life in Kyoto working as a doctor. Bonchō was one of Matsuo Bashō's leading disciples and, together with Kyorai, he edited the Bashō school's Monkey's Raincoat (Sarumino) anthology of 1689. He participated in numerous renku with Bashō and other members of his Shōmon school.
