Parque Barigüi, Public green space in Curitiba, Brazil.

Parque Barigüi is a large green space in the city with a lake, forests, sports fields, and walking paths spread across different landscapes. The grounds feature various areas for exercise, relaxation, and strolling throughout multiple sections.

Parque Barigui was created in 1972 as a linear park to control flooding and preserve native forest in the Barigui River basin. The land had earlier been a sesmaria granted to Baltasar Carrasco dos Reis, and later Mateus Leme took possession of a new sesmaria there. Old documents called the area Mariqui.

The name Barigui comes from the river crossing the park; in an indigenous language it means "river of the thorny fruit", referring to the pine cone, though another reading from Tupi mberu ("fly") and 'y ("water") gives "fly water". Old documents called the area Mariqui. The former Exhibition Center, created in 1975, was renamed Expo Renault Barigui in 2012 and later Centro de Eventos Positivo.

A public road cuts the park into two sections: forest with trails on one side, the lake on the other. A dedicated lane circles the lake for bicycles and rollerblades, and a long track serves walkers and runners. Kiosks with barbecues, restrooms and large car parks are on site.

The park's name comes from the Barigui River, which was dammed to create its 230,000-square-metre lake. In Tupi-Guarani, barigui can mean "river of the thorny fruit", referring to the pine cone of the Paraná pine, or alternatively "fly water", from mberu (fly) and 'y (water).
