Aunat (French pronunciation: [onat] ) is a commune in the Aude department in the Occitanie region of southern France.

Aunat is located some 60 km west by north-west of Perpignan and 25 km east by north-east of Ax-les-Thermes. Access to the commune is by the D20 road from Rodome in the west which passes through the village and continues east to Bessède-de-Sault. The D29 road comes from Fontanès-de-Sault in the south and passes through the length of the commune and the village before continuing north-west to join the D107 north-east of Belfort-sur-Rebenty. The commune is mostly rugged and forested but with farmland in the valley around the village.

The Ruisseau du Mouillou rises in the north-east of the commune and flows west gathering several tributaries from the north including the Ruisseau du Bernet and the Ruisseau de Valmajou before joining the Ruisseau de Romanis on the western border of the commune.
