The Campeonato Nacional de Velocidade (CNV, National Speed Championship) is a Portuguese motor racing competition, encompassing GTs, prototype racing cars and touring cars.

In 2007, the Campeonato Nacional de Turismos was created for S2000 cars.

In 2011, this championship ended because of lack of participants, so the GT cars went to race in the higher class.

Since 2010 the series has been organised by Full Eventos under the "Racing Weekend" brand.
