Lacq is a commune in the Pyrénées-Atlantiques department in south-western France.

It lies just northwest of the local capital of Pau.


In modern times the local economy has been based on the industrial use of subsurface petroleum reserves, and since 1951 on the extraction and development of a very large natural gas reservoir underneath the city. Processing of the large quantities of hydrogen sulfide in the gas have made Lacq a center of sulfur production.
