Rinchenia (named after Byambyn Rinchen) is a genus of oviraptorid dinosaur that lived in Asia during the Late Cretaceous epoch in what is now Mongolia, Nemegt Formation, around 70 million years ago.

Although concluding that it was distinctly different from Oviraptor in both skull and skeleton characters, Barsbold did not include a formal diagnosis for this new taxon.

The team also stated that even though the locality of the holotype is known, the exact site of discovery and horizon remains unknown.

[4] Funston in his 2019 master thesis described in extensive detail the holotype of Rinchenia, along with other oviraptorids, where he provided additional data regarding the name of the taxon.

The generic name, Rinchenia, is in honor of Byambyn Rinchen, veteran linguist and father of Barsbold.
