Jardín Botánico Chagual, Botanical garden in Santiago, Chile.

Jardín Botánico Chagual is a 33.9-hectare botanical garden in the Metropolitan Park of Santiago, in the Vitacura district. Its terrain includes flat zones, slopes, gorges and small hills. The garden is being developed around collections of Chilean Mediterranean-climate plants, including evergreen and deciduous trees and shrubs, bromeliads, and Amaryllidaceae and Liliaceae.

The garden is run by the Corporación Parque y Centro Cultural Botánico Chagual, a nonprofit municipal cultural corporation publicly announced in September 2002 and chaired by the Municipality of Vitacura, with members including the Ministry of Housing and Urbanism, the Metropolitan Park, INIA, Fundación Chile and the Corporación del Patrimonio Cultural de Chile. It was created to complement the native plant collections of the national botanical gardens of Viña del Mar and Valdivia, and in 2004 it received the Sello Bicentenario, a Chilean state award tied to the 2010 bicentenary.

The garden displays plants native to Chile's Mediterranean zone and serves as a place where visitors can discover the diversity of local plant life. This collection also helps schools and research institutions learn more about regional botany.

The garden lies in the Parque Metropolitano de Santiago, at Comodoro Arturo Merino Benítez N.º 3020, Vitacura, and is open every day of the year. Its terrain combines flat zones, slopes, gorges and small hills, so walking conditions change between sectors. The sources give no details on adapted paths or wheelchair access.

The garden focuses on preserving plants from Chile's Mediterranean zone, a region with special botanical importance. In this zone, many plant species grow naturally that are found nowhere else in the world.
