Athos-Aspis (French pronunciation: [atɔs aspis]; Occitan: Atòs e Aspins) is a commune in the Pyrénées-Atlantiques department, in the Nouvelle-Aquitaine region of south-western France.

The Arriouyeque flows from the east of the commune through the centre to join the Gave d'Oloron on the western border.

The Ruisseau de Rance rises just east of the commune and flows south-west to join the Arriouteque.

For Aspis Michel Grosclaude proposed a Gascon etymology es pins meaning "the pines".

At Athos there is a church of Romanesque origin in the old fief of Moliède d'Athos where there was a well-known ferry and ruins of a mill.

The cemetery has the tomb of the design engineer of the Sauveterre bridge and also that of Edmond Gourlat, consul of France and local personality.

Athos was the birthplace of Jean-Baptiste Boucho, born in the Bouchoô house in 1797, French Apostolic vicar of the Malay Peninsula.
