Appy is located some 15 km south-east of Tarascon-sur-Ariège and 12 km north-west of Ax-les-Thermes.

Appy is a remote mountainous commune, heavily forested in the south and west, with the rest alpine terrain.

In the north of the commune is the Etang d'Appy from which flows the Ruisseau de Lac d'Appy towards the south-west to join the Ruisseau de Caychax which joins the Ariège at Albiès. The eastern boundary of the commune is formed by the Ruisseau de Girabel which flows south joining with other streams to join the Ariege at Urs.
