Caldera Port (Spanish: Puerto Caldera), is the main freight port in the Pacific side of Costa Rica, located in the Esparza canton of the Puntarenas province.

There are two operating contiguous ports in the location, the regular container port with three docking areas, operated by Sociedad Portuaria de Caldera, and the newer grains port with only one docking area, operated by Sociedad Portuaria Granelera de Caldera and inaugurated in 2015.

[1] After the European colonization of the area, this was the main export and import region, using boats to transport the cargo from the shore to the ships.

A proper port was then built in the needle like peninsular area on which the Puntarenas canton and downtown city is now located, starting with wood materials in the 1910s and then steel in the 1930s.

[1] The main access highway from the Greater Metropolitan Area is the Route 27, which due to the port is also known as Autopista San José - Caldera (San José - Caldera Highway).
