The Seventh World Congress of the Communist International (Comintern) was a multinational conference held in Moscow from July 25 through August 20, 1935 by delegated representatives of ruling and non-ruling communist parties from around the world and invited guests representing other political and organized labor organizations. The gathering was attended by 513 delegates, of whom 371 were accorded full voting rights, representing 65 Comintern member parties as well as 19 sympathizing parties.

The gathering is best remembered for its endorsement of a Popular Front of communist and non-communist forces against the growing menace of fascism in Europe, paving the way for advocacy of collective security between the Soviet Union and the various capitalist states of Europe. This marked a dramatic reversal of the Comintern's previous orientation towards class warfare endorsed by the 6th World Congress of 1928, the aggressive line of the so-called "Third Period."
