No Platform was a British anti-fascist group formed in the mid 1990s by anti-fascists willing to carry on the militant "physical force" tradition of anti-fascism begun by the 43 Group and carried on by the 62 Group, some elements of the original Anti-Nazi League and then Anti-Fascist Action until the latter's retirement from militant anti-fascism in the mid-1990s.

The name comes from the "No Platform for Fascists" policy adopted by many trade and student unions in the late 1970s and the 80s. This policy is that the right to free speech does not extend to allowing fascists to hold public meetings or rallies or generally assemble in public due to the consequent risk to the right to free speech (or life) of those they would oppress and/or exterminate.
