The Mekong wagtail (Motacilla samveasnae) is a species of bird in the family Motacillidae. It was first described in 2001 and named in honour of the late Cambodian ornithologist Sam Veasna. It is a black and white bird, similar in appearance to the African pied wagtail, although their ranges do not overlap. Its facial features and distinctive voice distinguish it from other black and white wagtails in southeastern Asia.
The Mekong wagtail is found in the Mekong valley of Cambodia and Laos, and is a non-breeding visitor to Thailand and Vietnam. Its typical habitat is rocky areas beside fast-flowing stretches of river where seasonal flooding occurs. Although tolerant of humans, it is threatened by large scale alterations to its habitat such as inundation of riverine habitat following damming of the river.
