What was the worlds first oil producing country?

The world's first oil-producing country is generally recognized as the United States, where the first commercial oil well was drilled in Titusville, Pennsylvania, in 1859 by Edwin Drake. This marked the beginning of the modern petroleum industry. However, oil had been used for various purposes long before that in other regions, such as ancient Mesopotamia, but the U.S. was the first to develop a commercial extraction and production system.
