Maeda Matsu (前田 まつ) [known in Japan as o-Matsu no Kata (お松の方)](1547–1617) was a Japanese woman of the 16th century. She was the wife of Maeda Toshiie, who founded the Kaga Domain. Matsu had a reputation for intelligence; she was skilled at both literary and martial arts. Her sons—Toshinaga, Toshimasa, Toshitsune, Toshitaka, and Toshitoyo, who were each born throughout Matsu's marriage to Toshiie—were each allowed their own individual title of daimyo and their own private fief.
