Abidos is a Béarnais commune located some 13 km south-east of Orthez and 4 km north of Mourenx on the south side of the Gave de Pau. Access to the commune is by the D31 road from Le Bourguet in the north turning west in the commune to access the village and continuing southwest to join the D9. The D33 road from Noguères in the southeast passes through the commune east of the village and joins the D31 as it turns west. The commune has an industrial area in the southwest with the rest of the commune mainly farmland.

The Gave de Pau forms the north-eastern border of the commune and also passes through the northern corner of the commune as it flows north-west to join the Gave d'Oloron at Peyrehorade. The Baïse river flows through the centre of the commune from the southeast and joins the Gave de Pau in the commune. The Luzoué also flows from the southeast through the west of the commune to join the Gave de Pau.
