Aressy (; ) is a commune in the Pyrénées-Atlantiques department in the Nouvelle-Aquitaine region of south-western France. It is part of the urban area (unité urbaine) of Pau.
Aressy is located four kilometres south-east of Pau within the urban area of Pau. Access to the commune is by the D937 road from Pau which continues south-east to Meillon.
The Idelis bus route P23 stops at Aressy Clinic at Pôle Bosquet. The commune is also served by Route 835 of the Interurban network of Pyrénées-Atlantiques (Transports 64) between Bénéjacq and Pau, and by Route 805 between Lourdes and Pau.
Much of the commune is residential with some farmland and a large lake in the south.
The Gave de Pau flows north-west through the western part of the commune, and the Lagoin flows through the centre of the commune before joining the Gave de Pau just north-west of the commune.
Its name in Bearnais is Aressi (according to the classical norm of Occitan).
Brigitte Jobbé-Duval indicates that the place name could come from the Basque, meaning "place where there are rocks" which would confirm the hypothesis by Michel Grosclaude of ar- ("stone or rock") with the Basque locative suffix -etz transformed into -esse.
