Matsunaga Teitoku (松永 貞徳, 1570-1653) was a Japanese haikai and waka poet.

[1] Teitoku played a significant role in regularising the rules for Haikai, and in raising its importance and status as a genre.

[2] He specialised in elegant wordplay, and in subject-matter reflecting the Chinese classics and waka.

[4] Teitoku's approach was criticised by the Danrin school for shallowness and excessive wordplay.

[5] One member, Bashō himself, is reported to have said of its founder, Nishiyama Sōin, that, if not for him, "we would still be licking the slaver of aged Teitoku".
