Arlebosc (French pronunciation: [aʁləbɔsk]; Occitan: Arlabòsc) is a commune in the Ardèche department in the Auvergne-Rhône-Alpes region of southern France.

Access to the commune is by the D578 road from Saint-Jeure-d'Ay in the north passing through the village and continuing west then south-west to join the D534 north-west of Lamastre.

The Ruisseau de Balaye forms the western border as it flows south to join the Doux.

The Merdenc rises in the north of the commune and forms part of the northern border as it flows north-east to join the Daronne south-east of Saint-Félicien.

The French term for cranberry (Airelle) is considered to be a borrowing from a variant of the Massif Central or the Alpine éiréla (also airelo).
