The Nakajima Sakae (栄, "Prosperity") was a two-row, 14-cylinder air-cooled radial engine used in Japanese aircraft during World War II. "Sakae" was the navy designation; the army called the first of the series the Ha-25 (ハ25) and later versions were designated Ha105, Ha115. Navy designations were Sakae 10, 20 and 30 series.

A total of 21,166 were made by Nakajima; 9,067 were manufactured by other firms.
