Allan-Roméo Nyom (born 10 May 1988) is a Cameroonian professional footballer who plays for Granada CF on loan from Udinese Calcio, as a right defender.

Born in Neuilly-sur-Seine, France, Nyom only played amateur football in the country, competing in the reserves championship with AS Nancy-Lorraine and appearing for AC Arles-Avignon in the Championnat National.

In the 2009 summer he was signed by Udinese Calcio in Italy, being immediately loaned to Granada CF in Spain as part of the partnership agreement between both clubs.

Nyom quickly became an undisputed first-choice with the Andalusia club, helping it promote from Segunda División B to La Liga in just two seasons.

He made his debut in the latter competition on 27 August 2011, in a 0–1 home loss against neighbours Real Betis.

Nyom renewed his contract with Udinese in late May 2013, but continued playing with Granada.
