Bassillon-Vauzé is located some 25 km north-east of Pau and 8 km west of Maubourguet. The eastern border of the commune is also the departmental border with Hautes-Pyrénées. Access to the commune is by the D68 from Vidouze in the east which changes to the D148 at the departmental border and continues through the south of the commune west to join the D943 south-west of the commune. The D205 comes from Corbère-Abères in the north which passes through the commune and continues south to join the D148 in the south of the commune. The commune is mostly farmland with some forest in the west.

The Larcis river and the Lac de Bassillon, which is formed by a dam on the Larcis, form the eastern border of the commune. The Ruisseau du Boscq forms the western border of the commune as it flows north into the lake formed by the Retenue de Lembeye-Corbères dam.

Michel Grosclaude said that Bassillon comes from the Latin name Bassilius with the suffix -onem, giving "Domain of Bassius". The origin of Vauzé is undetermined.

On page 173 he mentioned that Vauzé had a lay abbey, vassal of the Viscount of Vauzé, and that the Barony of Vauzé was created in 1641 under the Viscounts of Béarn which included Peyrelongue-Abos and Vauzé.

The former communes of Bassillon and Vauzé were merged in 1833.
