Puerto San José is a town on Guatemala's Pacific Ocean coast, in the department of Escuintla.

It has a population of 23,887 (2018 census),[1] making it the largest town along the Pacific coast of Guatemala.

It was the Pacific port for Guatemala, but this was superseded in the 20th century by Puerto Quetzal, four kilometres to the east of the town.

The local tourist industry caters largely for weekenders from Guatemala City.

Puerto San José has a tropical savanna climate (Köppen: Aw) with a wet season from May to October, and a dry season from November to April.
