Miramar is a district of the Montes de Oro canton, in the Puntarenas province of Costa Rica. The inhabitants of the Miramar district are officially known as Miramareños. The region is recognized for its extensive natural landscapes and its prominent role as a major center for national sports.
Historically, the community of Miramar was known by the name Los Quemados (The Burned Ones). Two primary theories exist regarding the origin of this designation: the first suggests it referred to the unique coloration of the local mountains, which gave the visual impression of having been scorched; the second attributes the name to the annual practice of hunters setting fire to the hillsides.
The modern name, Miramar, was proposed by Francisco de Paula Amador during a visit to the region, inspired by the panoramic views of the Gulf of Nicoya visible from the area. According to Executive Decree No. 18, issued on April 23, 1897, the name 'Los Quemados' was officially replaced by 'Montes de Oro' for the district, while 'Miramar' was designated for the primary administrative center.
