Ikeda Tsuneoki (池田 恒興?, 1536 – May 18, 1584), also known as Ikeda Nobuteru (池田 信輝), was a daimyo and military commander during the Sengoku period and Azuchi-Momoyama period of the 16th century of Japan. He was a retainer of the famous warlords Oda Nobunaga and Toyotomi Hideyoshi. His father was Ikeda Toshitsune, who served Oda Nobuhide. There are various theories as to his birthplace (including Owari, Mino, Settsu and Ōmi provinces).
He was one of the four karō at Kiyosu Castle. His official position was Kii-no-kami (紀伊守), or "Governor of Kii Province". His courtesy name was Shōzaburo (勝三郎). He later became a priest, and referred to himself as Shōnyu (勝入). In his early years, he served Nobunaga, since his mother was a foster mother of Nobunaga. In 1570, he was active in the Battle of Anegawa and became the lord of Inuyama Castle. After that, he took part in various battles, such as the Battle of Nagashino against the Takeda clan.
