The Primera División Uruguaya 2005 started on 5 March 2005 and ended on 12 July 2005.
The league was a single round-robin tournament and not relegation and promotion from Segunda División Uruguay. But along with Apertura 2005 of 2005–06 season, the whole schedule of 2005 would count in a final table, and the bottom three would be directly relegated. The winners qualified for the 2006 Copa Libertadores.
