The following are former United States district courts, which ceased to exist because they were subdivided into smaller units. With the exception of California, each of these courts initially covered an entire U.S. state, and was subdivided as the jurisdictions which they covered increased in population. Two of the district courts—those of South Carolina and New Jersey—were subdivided but later recreated. Every change to the divisions and boundaries of these courts is effected by an act of the United States Congress, and for each such action, the statutory reference is identified.
