Jardín botánico La Carolina, Botanical garden in Santo Domingo de los Tsáchilas, Ecuador.

Jardín botánico La Carolina is a 17-hectare garden (42 acres) with sections dedicated to palms, orchids, medicinal plants, and fruit trees that display Ecuador's tropical plant diversity. Each zone is organized to show different aspects of the region's vegetation.

The site originated in 1996 when the Juan Eulogio Paz y Miño cooperative donated 10 hectares of land to the Diocese of Santo Domingo. What began as an initial gift grew into the current botanical project over time.

The name La Carolina honours a Swiss woman named Carolina who did social work for the Diocese of Santo Domingo; Bishop Emilio Lorenzo Stehle chose it. In 2010 the garden was renamed Jardín Botánico Padre Julio Marrero, after the second rector of the Pontificia Universidad Católica del Ecuador's Santo Domingo campus, who died on 28 July 2009.

The garden lies in Santo Domingo de los Colorados, a wet tropical climate with roughly 22.9 °C average temperature and 3000–4000 mm of rain a year, so bring rain protection. Paths link the palm collection, the croton avenue, the 500-metre cucarda maze, the jungle trail and the orchid house. The nurseries and the research and interpretation centre, with its library, are on site.

The garden's name honours a Swiss volunteer called Carolina, remembered by Monsignor Emilio Lorenzo Stehle for her social work with the Santo Domingo diocese. The current name, Padre Julio Marrero, dates from 2010 and commemorates the second rector of the PUCE Santo Domingo campus, who died on 28 July 2009.
