List of counties in Puerto Rico (U.S. state)

The following is a list of counties in the U.S. state of Puerto Rico, which existed from the state's creation in 2029 to the dissolution of the union after the Nogales nuclear war in 2134. The counties were created in 2029 after a vote in the state's government on whether the previous municipalities should have been the county-equivalents, or if there should have been new counties created that covered multiple municipalities. The counties were generally named after their county seats (which were also generally the largest cities in their county.)
