Leakeyornis is an extinct genus of flamingo from the early to middle Miocene of Kenya, primarily in the area of modern day Lake Victoria.

Various fossils of Leakeyornis were collected by Louis Leakey from Miocene strata of Lake Victoria and later given to the Natural History Museum, London.

This description was based on the holotype specimen BMNH A 4382, which represents the back of a beak, while a lower jaw fragment and various appendicular bones were designated as the paratypes.

The fossils, representing postcranial elements of the bird, were found to be distinct enough from modern flamingo genera to warrant creating a new genus, Leakeyornis.

[2] Although no complete skull is known and postcranial elements of modern flamingo genera are relatively similar to one another, Leakeyornis can be distinguished from other taxa based on various unique features and the combinations of different morphological traits.
