La Desembocadura y Estuario del Río Maipo (Maipo River Delta and Estuary) is located between the towns of San Antonio and Santo Domingo in the San Antonio Province, Region of Valparaiso, Chile. The approximately 140-hectare (346-acre) site includes sections of beach, sand bars, estuary, grasslands, wetlands, shrublands, dunes, and river mouth. A total of 132 species of birds have been recorded within this ecosystem, plus many fish, reptiles, amphibians, and mammals.

The area was designated a WHSRN Site of Regional Importance for hosting more than 1% of the biogeographic population of two species: Whimbrel (Numenius phaeopus) and the pitanay subspecies of American Oystercatcher (Haematopus palliatus).

La Desembocadura y Estuario del Río Maipo is the fourth WHSRN site in Chile, joining Humedal del Río Lluta in Arica, Humedales Orientales de Chiloé on Chiloé Island, and Bahía Lomas in Tierra del Fuego.
