Rampant France took control of the Six Nations title race as they scored 34 unanswered points to beat Ireland in Dublin and end the home side's Grand Slam hopes.
Despite losing captain Antoine Dupont to injury after 30 minutes, France scored three second-half tries to move two points clear of Ireland at the top and avenge last year's defeat in Marseille.
Tournament top scorer Louis Bielle-Biarrey crossed twice for Les Bleus while Paul Boudehent, Oscar Jegou and Damian Penaud all crossed in a stunning bonus-point triumph.
Dan Sheehan's early second-half try put Ireland - who temporarily lost Joe McCarthy and Calvin Nash to yellow cards in either half - 13-8 up but France's response was emphatic as they put themselves in pole position before hosting Scotland in their final game.
