Liga IV Bucharest is the municipal football division of Liga IV for clubs based in Bucharest, Romania. The competition is ranked as the fourth tier of the Romanian football league system and is organized by AMFB Bucharest – Asociația Municipală de Fotbal (lit. 'Municipal Football Association').
It is contested by a variable number of teams, depending on the number of teams relegated from Liga III, the number of teams promoted from Liga V Bucharest, and the teams that withdraw or enter the competition. The winner may or may not be promoted to Liga III, depending on the result of a promotion play-off contested against the winner of a neighboring county series.
