The New Guinea singing dog, or New Guinea Highland dog, is a rare dog native to the New Guinea Highlands of the island of New Guinea. Its taxonomic status is debated, though it is closely related to the dingo. It is classified as either Canis lupus dingo or Canis familiaris, and is in the same clade as the domestic dog and the dingo.

The dog is noted for its unique vocalization. Little is known about New Guinea singing dogs in the wild, and until 2016 there were only two photographs of wild sightings: one taken in 1989 and published by Australian mammalogist Tim Flannery, and the other taken in August 2012 by wilderness adventure guide Tom Hewett in the Star Mountains region of West Papua.

In 2016, the New Guinea Highland Wild Dog Foundation announced to the media that it and the University of Papua had located and photographed a group of fifteen "highland wild dogs".

Reports from local sources in Papua New Guinea from the 1970s and the mid-1990s indicate that singer-like wild dogs found in New Guinea, whether they were pure singers or hybrids, fed on small to middle-sized marsupials, rodents, birds and fruits.

Attitudes towards New Guinea singing dogs differ, but hybridization with the domestic dog, and thus watering down of the genes needed to maintain purity, is one of the main threats to the species's continuation. It shares this problem with the dingo.
