The Shiba clan (斯波氏 Shiba-shi) was a Japanese clan that descended from the Seiwa Genji.
The Shiba were descended from the Minamoto and during the Muromachi period were an influential shugo family that ruled the provinces of Owari and Echizen.
However, the clan had an internal diatribe between factions during the mid-15th century and failed to maintain their Daimyō status and lost the Echizen province to the Asakura clan in 1470.
In 1550 the Shiba were represented by Shiba Yoshimune of Owari province through whom the Iwakura branch of the Oda clan ruled. Yoshimune had his abode at Kiyosu Castle.
Yoshimune was killed in 1554 by Oda Nobutomo. Shiba Yoshikane (died 1600) was the son and heir of Shiba Yoshimune.
