Truco, a variant of Truc, is a trick-taking card game originally from Valencia and the Balearic Islands, popular in South America and Italy. It is usually played using a Spanish deck. Two people may play, or two teams of two or three players each.

It is played in Occitania, Sarthe (where it is known as trut), Poitou (tru) and the Basque Country (truka), and is still very popular in the Valencia region (joc del truc). More elaborate versions are widely played in Argentina, Uruguay, Venezuela, Paraguay and Brazil under such names as Truco, Truque and Truquiflor.
