Oil and Gas Law in the United States is the branch of law that pertains to the acquisition and ownership rights in oil and gas both under the soil before discovery and after its capture, and adjudication regarding those rights.

The law regulating oil and gas ownership in the U.S. generally differs considerably from laws in Europe because oil and gas are often owned privately in the U.S. as opposed to being owned by the national government in numerous other countries. In the U.S., extraction of oil and gas is by and large regulated by the individual states through statutes and common law. Federal and constitutional laws do apply as well.
