The Jones Law was an Organic Act passed by the United States Congress. The law replaced the Philippine Organic Act of 1902 and acted as a constitution of the Philippines from its enactment until 1934, when the Tydings–McDuffie Act was passed. The Jones Law created the first fully elected Philippine legislature.

The Philippine Organic Act was a basic law for the Insular Government that was enacted by the United States Congress on July 1, 1902. It is also known as the Philippine Bill of 1902 and the Cooper Act, after its author Henry A. Cooper. The approval of the act coincided with the official end of the Philippine–American War.
