The Crested pigeon (Ocyphaps lophotes) is an Australian species of pigeon. Only two Australian pigeon species possess an erect crest, the Crested pigeon and the spinifex pigeon. The Crested pigeon is sometimes referred to as a Topknot pigeon, a common name shared with the reddish crested Lopholaimus antarcticus of Eastern Australia. Common names for the species, aside from crested or Topknot pigeon, characterize them as a 'bronzewing' or 'dove' that is likewise distinguished by the crest.

Crested pigeons are found throughout mainland Australia except for the far northern tropical areas. They live in lightly wooded grasslands in both rural and urban areas, and can also visit watercourses, homestead gardens, grain farming areas, pastoral areas, sports grounds, and golf courses.

Crested pigeons are highly social birds and often gather in flocks of varying sizes. They are active during the day but prefer to forage in the morning and in the evening. They forage in small to large groups, which also gather to drink at waterholes. The most distinctive behavior of Crested pigeons is the beating and whistling sound their wings make when they take off. This is most likely to draw the attention of predators to birds on the wing, and away from any birds remaining on the ground, and as an alarm call to other pigeons. When the birds land, their tails tilt upwards and the flight patterns are similar to those of the Spotted turtle dove. If startled, Crested pigeons take to the air producing a distinctive whistling 'call'.

Crested pigeons are monogamous and form pairs. They breed throughout the year, with the peak in the warmer months. Males perform a courtship display to attract the female by displaying an elaborate mating dance; they bob their bodies up and down while opening and closing their wings like a fan with each bob. This is accompanied by a soft hooting which is timed with the bobbing. Crested pigeons usually nest in shrubs or trees constructing a platform of twigs. The female lays 2 oval, white, glossy eggs and both parents incubate them for about 3 weeks. For another 3 weeks, both parents will feed and protect their chicks until they are ready to leave the nest.
