Tramezaïgues (French pronunciation: [tʁamza.iɡ], official name[3]) or Tramezaygues (local name) is a commune in the Hautes-Pyrénées department, in the Occitanie region of France.

[3] The commune of Tramezaïgues, in the south of the Hautes-Pyrénées department, extends from the Aure Valley to the Spanish border.

The name of Tramezaïgues is derived from the Latin description: inter ambas aquas (between two waters).

To the north of the village is the Pla d'Adet ski resort, and Aragnouet is to the west.

The château was a position for monitoring the Spanish border until the French Revolution.
