Guayana Province covered a territory roughly equal to the present day country of Guyana and the Venezuelan Guayana Region from 1591 to 1739, when the province's territory was merged into the Spanish Trinidad-Guayana Province, along with Trinidad Province (present day Trinidad and Tobago).
Amazonas is named after the Amazon River, and was formerly part of the Spanish Viceroyalty of Peru, a region called Spanish Guyana. It was settled by the Portuguese in the early 18th century and incorporated into the Portuguese empire after the Treaty of Madrid in 1750. It became a state of the Brazilian Republic in 1889.
Guayana Province was within the Spanish colonial New Andalusia Province from its establishment in 1585 to 1776, when it was incorporated into the new Captaincy General of Venezuela. It was also within the larger jurisdiction of the Viceroyalty of New Granada (1717–1819).
After the Venezuelan War of Independence (1811–1823) it was a province in new nation of Venezuela until 1864.
