The Legislature XV of Italy () started on 28 April 2006 and ended on 28 April 2008. Its composition resulted from the election of 9–10 April 2006, called after President Ciampi dissolved the houses on 11 February 2006, at the end of the previous legislature. This legislature was the second shortest in the history of the Italian Republic, lasting exactly two years, and ending when President Giorgio Napolitano dissolved the houses on 6 February 2008, after a vote of no confidence on the incumbent Prodi Cabinet.

The election was the first one with the new preferential block electoral system (also known as Porcellum) introduced by Roberto Calderoli in 2005, and later declared partially unconstitutional by the Constitutional Court.
