A federal capital is a political entity, often a municipality or capital city, that enjoys status as a seat of government in a federal state.

 Federal capitals may or may not be considered states in themselves, and either exercise significant political autonomy from the federation or are directly ruled by the national government located within their premises, as federal districts.
