The Coastal Venezuelan mangroves ecoregion (WWF ID: NT1408) covers the salt-water mangrove forests along the Caribbean Sea and Atlantic Ocean coast of Venezuela, from Cocinetas Basin (on the western border with Colombia) to the edge of the Caño Manamo River and the Orinoco Delta in the east.

It is one of the largest mangrove ecoregions in South America, with an area of 5,698 km2, and stretching across over 400 km of Venezuelan coastline.

The sites on the western, Caribbean, coast are drier and often have a savanna-like character.

The eastern sites, on the Atlantic Ocean coast from the Gulf of Paria to the western edge of the Orinoco Delta, is wetter with precipitation up to 2,000 mm/year.

Associated vegetation includes thorn scrub woodlands, coastal evergreen trees, ferns (Acrostichum aureum) and mallows of genus Malvaceae, such as coastal hibiscus Hibiscus tiliaceus.
