The Moist Pacific Coast mangroves ecoregion (WWF ID:NT1423) covers a series of disconnected mangrove sites along the Pacific Ocean coast of Costa Rica and Panama.

The area is in a transition zone from the drier coastline to the north; rainfall in this ecoregions is over 2,000 mm/year, and reaches over 3,600 mm/year at the southern end.

[1][2][3] The mangroves of this ecoregion are found along a 500 km stretch of coastline, from Jacó, Costa Rica to southwest corner of the Azuero Peninsula in Panama.

[5][6] The mangroves in this ecoregion are more fully developed than those farther north, both because of the higher precipitation and because of the greater amounts of freshwater and sediments received from the runoff of the Talamanca Mountain Range immediately inland.

The mangrove hummingbird (Amazilia boucardi) and yellow-billed cotinga (Carpodectes antoniae) are endemic to the ecoregion.
