Horio Tadaharu (堀尾 忠晴; 1596 – 26 October 1633) was a tozama daimyō in Japan during the Edo period. His father was Horio Tadauji and his grandfather was Horio Yoshiharu. He was the third leader of the Matsue clan. In 1633, Tadaharu died. The main line of the Horio clan thus came to an end; however, a branch of the family became retainers of the Matsudaira clan over the Matsue Domain. There is a wooden statue of Tadaharu at Enjō-ji Temple [1] in Matsue.
