Serie D is the top level of the Italian non-professional football association called Lega Nazionale Dilettanti. The association represents over twelve thousand football players and four hundred football teams across Italy. Serie D ranks just below Lega Pro Seconda Divisione (the 4th and last professional league), and is thus considered the 5th ranked league in the country. It is organized by the Roman Comitato Interregionale (Interregional Committee), a "league in the league" inside the LND.
