Pasaia (Spanish: Pasajes) is a town and municipality located in the province of Gipuzkoa in the Basque Autonomous Community of northern Spain.

It is a fishing community, commercial port and the birthplace of the famous admiral Blas de Lezo and of the fashion designer Paco Rabanne.

The municipality numbers 16,056 inhabitants (as of 2008[update] estimates), clustering around the Bay of Pasaia in four nuclei, namely Pasai San Pedro, Pasai San Juan (or Donibane in Basque), Antxo and Trintxerpe, with each part showing distinctive features.

[3] It was a major source of revenue for the municipal coffers on the strength of its position on commercial sea routes.

Trintxerpe and Antxo eventually became a continuous urban strip with the eastern districts of Donostia.
