The Matsunaga clan (松永氏, Matsunaga-shi) is a Japanese Samurai Clan who are descended from the Fujiwara clan.^[1][2]

The lineage of Matsunaga Danjo Hisahide strengthens the Matsunaga clan's claim to Fujiwara lineage through Hisahide's nephew, Tadatoshi Naito (also known as Naito Joan and Fujiwara John). Tadatoshi Naito's mother was Naito Sadafusa who was from the Naito clan. The Naito clan is descended from Fujiwara no Hidesato (Hokke (Fujiwara)). Tadatoshi Naito would serve as lord of Yagi castle.^[3]

Hisahide's granddaughter, Matsunaga Teitoku (松永貞徳 ^[ja]) also strengthened the Matsunaga clan's link to the Fujiwara clan. Her mother was the older sister of Fujiwara Seika (藤原惺窩). Teitoku's cousin was Tadatoshi Naito.^[4]

Other sources suggest that the Matsunaga clan descended from the Minamoto clan and via Takenouchi no Sukune, himself a descendant of Emperor Kogen. Sukune called himself Matsunaga Ki, after Matsunaga no sho, the domain of Onyu, in Wakasa Province. This means the Matsunaga clan is descended from the Ki clan, one of the noble clans.^[5]
