In 2014, the type species Mercuriceratops gemini was named and described by Michael Ryan, David Evans, Philip John Currie and Mark Loewen. The generic name combines the name of the Roman god Mercury, a reference to the similarity of the neck shield to the winged helmet of the messenger of the gods, with ~ceratops, horn face, a usual suffix in ceratopian names. The specific name is that of the constellation Gemini, named after the twins Castor and Pollux, in reference to the similar specimens the species is based on.
