Lady Hayakawa (早川殿, Hayakawa-Dono, died April 4, 1613) was a Japanese aristocrat of the Sengoku period. Hayakawa is a common nickname for one of Daimyō Hōjō Ujiyasu's daughters, who lived in the Sengoku through early Edo periods. She is best known for marrying into the Imagawa clan as a condition for The Kōsōsun Triple Alliance, an alliance which put daughters of the Takeda, Imagawa and Hojo clans into political marriages. The formation of the alliance would later change the fate of these three powerful clans.
