Poza Rica, formally: Poza Rica de Hidalgo is a city and its surrounding municipality in the Mexican state of Veracruz. Its name means "rich well/pond". It is often thought that the name came to be because it was a place known for its abundance of oil. In reality, before oil was discovered, there existed a pond rich in fish, which gave origin to the city’s name. In the 20th century oil was discovered in the area. It has since been almost completely extracted.
