Mayaro is the name of acounty on southeasternTrinidad island, inTrinidad and Tobago.

The "Mayaro District" was the first area of settlement on the east coast. Many estates were granted toFrench planters who settledTrinidad in the late 18th century. No roads crossed the island and the area was only accessible by steamer until the late 19th century.
The name Mayaro is applied to several villages along the coast. Thecounty of Mayaro occupies a large area of southeastern Trinidad, but the name is usually only applied to the coastal strip. County Mayaro is divided into twowards: Trinity andGuayaguayare.
Along this strip a number of villages exist to which the name Mayaro is generally applied. From north to south these are: Kernaham/Cascadou,Ortoire, St. Joseph, Beau Sejour, Plaisance, Pierreville, Beaumont, St. Ann's, Radix, Ste. Marguerite, Lagon Doux, Grand Lagoon and Lagon Palmiste. Beyond that are several small villages and then the town of Guayaguayare.
