Hyuganatsu (Citrus tamurana, Japanese: 日向夏) is a citrus fruit and plant grown in Japan. The name comes from Hyūga, the ancient name of Miyazaki Prefecture in Kyushu, where the citrus is said to have originated, while "natsu" (夏^?) means summer. Hyūganatsu grown outside Kyushu are sometimes shipped under different names such as Konatsu (小夏^?), Tosakonatsu (土佐小夏^?), or New Summer Orange (ニューサマーオレンジ^?).

A hyūganatsu sapling was said to have suddenly been found in a Miyazaki garden sometime in the 1820s, after which it became widely cultivated throughout the region. It is theorized to be either a mutated yuzu or perhaps more likely, a chance hybrid between yuzu and pomelo.
