The statement from President Nicolas Sarkozy's office did not say how, when or where the Zambian leader had died.
Mwanawasa had been hospitalized in France since suffering a stroke in June. Zambian state media said earlier Tuesday that his condition had suddenly taken a turn for the worse.
Mwanawasa won praise for his anti-corruption and economic modernization drive in one of the world's biggest copper producers but failed to lift the Zambian people out of crushing poverty.
Sarkozy called his death ``a great loss for the African continent'' and for democracy.
