凤头鸠（学名：Ocyphaps lophotes）是一种生活在澳洲大陆的鸟。除澳大利亚北部靠赤道地区外它在整个澳大利亚生活，长30至34厘米。这种鸟栖息在草地、灌木丛和林地中海，但在河边、园子、牧场、运动场和高尔夫球场上也可以看到它。由于人的活动，在澳大利亚创建牧场等，使得它的栖息地变广（一开始它只生活在澳大利亚西部）。由于这种鸟食草籽，它们尤其喜欢生活在粮田附近。

凤头鸠的羽毛总体来说是带有棕色的灰色。它的头顶上有一簇黑色的羽冠。在凤头鸠奔跑时这簇羽冠直立。眼睛周围有一圈鲜艳的、橙色的环。翅膀上是青铜色，带有黑色的条纹。凤头鸠的少数羽毛带有鲜艳的棕色、紫色、蓝色和绿色。幼鸟的羽毛颜色比较暗淡，翅膀上没有青铜色。

The crested pigeon (Ocyphaps lophotes) is a bird found widely throughout mainland Australia except for the far northern tropical areas. It is the only member of the genus Ocyphaps. There are only two Australian pigeon species that possess an erect crest, being the crested pigeon and the spinifex pigeon. The crested pigeon is the larger of the two species. The crested pigeon is sometimes incorrectly referred to as a topknot pigeon, however the topknot pigeon, or Lopholaimus antarcticus is a different species altogether, and has a red-brown crest that does not stand erect.
