The Nanyang Basin (simplified Chinese: 南阳盆地; traditional Chinese: 南陽盆地; pinyin: Nányáng Péndì; Jyutping: Naam4joeng4 Pun4dei6) is a major river basin, principally of the Han River (simplified Chinese: 汉水; traditional Chinese: 漢水; pinyin: Hàn Shuǐ; Jyutping: Hon3 Seoi2), located in the central inland part of the People's Republic of China, and thus forms part of the Middle Yangtze region. Much of its northern section is administered by Henan Province, with a smaller southern region of the basin lying in Hubei Province. Its total area is 46291 square kilometers, and it is one of the most populous basins in China, with around 20 million residents.
