Nadaism was a countercultural movement with roots in Dadaism and Surrealism. It expressed a protest against the traditional institutions of society and culture, a protest that is philosophically nihilist.

It was formed mainly by young, irreverent Colombians who, with the motto of "no faith will be left untouched nor any idol in its place," took the lead of the local poetry of those times. Although it happened at the same time than some other manifestations of Latin American literature, it is one of the few purely countercultural movements fully rooted in the region.

Representative figures of the movement include Gonzalo Arango, its founder, writer of De la Nada al Nadaísmo, and Fanny Buitrago.
