Ilokelesia is an extinct genus of abelisaurid theropod,[1] preserved in the layers of the earliest Late Cretaceous[2] of the Huincul Formation, Neuquén Group, located near Plaza Huincul, Neuquén Province, Argentina.

The specimen, consisting of very fragmentary elements of the skull and the axial and appendicular skeleton, was described by Rodolfo Coria and Leonardo Salgado in late 1998.

[3] The generic name's etymology is derived from the Mapuche language, ilo meaning "flesh" and kelesio, "lizard"; while the specific descriptor reflects the name of the locality where the fossil was found, Aguada Grande.

In 2010 Gregory S. Paul gave a length of 4 meters (13 ft) and a weight of 200 kg (440 lbs).

[4] In 2016 it was estimated to be 5.3 metres (17 ft) in length in a comprehensive analysis of abelisaur size.
