Baleix is a commune of the Pyrénées-Atlantiques department in the Nouvelle-Aquitaine region of south-western France.

Baleix is located in the Montanérès overlooking the Lées Valley some 26 km north-east of Pau and 10 km south of Lembeye. Access to the commune is by the D7 road from Saint-Jammes in the west which passes through the length of the commune and the village and continues east to Casteide-Doat. The D145 comes from Lespourcy in the south-west and passes through the village to continue north to Anoye. Apart from the village there is also the hamlet of Tisné north-east of the village. The commune is mostly farmland with a few scattered small forests.

The Lées flows through the east of the commune from the south and continues north to join the Adour near Aire-sur-l'Adour. The Petit Lées comes from the south and flows north-east through the commune to join the Lées.

Michel Grosclaude said that etymologically the name comes from the Gascon Balèch meaning "plateau".

The commune has long been occupied as evidenced by the discovery of a fortified camp surrounded by a moat with visible remains of earthworks.

During the medieval period the commune was a member of the Commandery of the Order of Malta of Caubin and Morlaàs.
