The Situationist Antinational was an American magazine formed in 1974, two years after the disbanding of the Situationist International.

It was largely abandoned for the Debordian theory of the spectacle after the Second Situationist International and Situationist Antinational were formed.

After an intense period of theoretical analysis, publication and the expulsion of most of its few members, leading to the Second Situationist International, the Situationist Antinational and the Situationist Bauhaus, Debord dissolved the SI in 1972.
