栗翅鹰（学名：Parabuteo unicinctus；Harris Hawk、Bay-winged Hawk、Dusky Hawk），又名哈里斯鹰，是一种中至大型的猛禽。牠们分布在美国西南部至智利和阿根廷中部。牠们有时会在西欧，尤其是英国出没，但很多相信都是从饲养中逃走的。

栗翅鹰是栗翅鹰属下的唯一物种。其属名是由希腊文的「拟似」及拉丁文的「秃鹰」组合而成，种小名是根据其尾端上的白间所取。约翰·詹姆斯·奥杜邦以其好友及经济支持者爱德华·哈里斯（Edward Harris）来取其英文名。牠们最著名的行为是会成群合作猎食。

The Harris's hawk (Parabuteo unicinctus) formerly known as the bay-winged hawk or dusky hawk, is a medium-large bird of prey that breeds from the southwestern United States south to Chile and central Argentina. Birds are sometimes reported at large in Western Europe, especially Britain, but it is a popular species in falconry and these records almost certainly all refer to escapes from captivity.
