Kimura Shigenari (木村 重成, 1593 – June 2, 1615) was a Japanese samurai of the early Edo period. A retainer of the Toyotomi clan, Shigenari fought at the Siege of Osaka (leading Toyotomi forces at the Battle of Imafuku) and died in battle. Kimura Shigenari was a son of Kimura Shigekore, also known as Kimura Hitachi no suke (vice-governor of Hitachi), one of the chief counselors of Toyotomi Hidetsugu, but much of his origin remains uncertain. His mother was Toyotomi Hideyori's wetnurse: that was why Shigenari was able to become Hideyori's page at an early age and his vassal later.
