Tévennec Lighthouse (French: Phare de Tévennec) is a lighthouse located at the western tip of Brittany (département of Finistère), in the northern part of the Raz de Sein off the Pointe du Van. Automated in 1910, it accompanies the light of La Vieille in securing the passage of the Raz de Sein, which presents many difficulties. The rocks near Tévennec were historically known as Stevenet Banks.

It was listed as a monument historique by a decree of December 31, 2015.
