Kanamori Nagachika (金森 長近, 1524 – September 20, 1608) was a Japanese samurai who lived from the Sengoku period into the early Edo period. He was the first ruler of the Kanamori clan and served as a retainer of the Oda, Toyotomi, and Tokugawa clans. Later in his life, he also became a daimyo.
Nagachika first served the Saitō clan of Mino Province; however, after their demise, he became a retainer of Oda Nobunaga. During this time he served as the ruler of Matsukura Castle and Takayama Castle.
Nagachika was also a tea master and an admirer of Sen no Rikyū. After Toyotomi Hideyoshi ordered Rikyū's death, Nagachika sheltered Rikyū's son Sen Dōan.
