Cérilly (French pronunciation: [seʁiji]) is a commune in the Allier department in central France.

It is in close proximity to the largest and oldest untouched oak forest in western Europe: the Forest of Tronçais.

Many oak trees exceed 250 years in age.

It is now a state forest which supplies much of the choice oak used in making the best wine barrels that are used mostly in Burgundy.

Cérilly is located in the bocage bourbonnais natural region, spanning a sixth of la Forêt de Tronçais.
