The Reeves's Pheasant, Syrmaticus reevesii, is a large (up to 210 cm long) pheasant within the genus Syrmaticus. It is endemic to China.

The name commemorates the British naturalist John Reeves, who first introduced live specimens to Europe in 1831.

The male is a brightly plumaged bird with a scaled golden white and red body plumage, grey legs, brown iris and red skin around eye. The head is white with a black narrow band across its eyes. The male has an extremely long silvery white tail barred with chestnut brown.

This spectacular pheasant is mentioned in the Guinness World Records 2008 for having the longest natural tail feather of any bird species; a record formerly held by the Crested Argus Pheasant. It can measure up to 2.4 metres or 8 feet (2.4 m) long.

The female is a brown bird with blackish crown, buff face and grey brown barred tail feathers. The hen Reeves's Pheasant is the same size as a male Common Pheasant.

There are no known subspecies but there is some variation in plumage.
