The United States district courts are the trial courts of the U.S. federal judiciary. There is one district court for each federal judicial district. Each district covers one U.S. state or a portion of a state. There is at least one federal courthouse in each district, and many districts have more than one. District court decisions are appealed to the U.S. court of appeals for the circuit in which they reside, except for certain specialized cases that are appealed to the U.S. Court of Appeals for the Federal Circuit or directly to the U.S. Supreme Court.
The 94 United States district courts are the general trial courts of the United States federal court system. Both civil and criminal cases are filed in the district court, which is a court of law, equity, and admiralty. There is a United States bankruptcy court associated with each United States district court. Each federal judicial district has at least one courthouse, and many districts have more than one. The formal name of a district court is "the United States District Court for" the name of the district—for example, the United States District Court for the Southern District of New York.
