Yahagi (やはぎ) is a frigate of the Japan Maritime Self-Defense Force, and the fifth ship of the Mogami class. Her namesake comes from the Yahagi River, which flows through Nagano, Gifu, and Aichi prefectures, a name that was chosen by Defense Minister Nobuo Kishi after a competition within the Maritime Self-Defense Forces.

She is the third Japanese warship to bear this name, following the former Imperial Japanese Navy's Chikuma-class cruiser Yahagi of 1911, and the Agano-class cruiser Yahagi of 1942, though the kanji characters are different, as the former Imperial Japanese Navy's Yahagi was named after the old name of the Yahagi River.
