Libertære Socialister (abbreviated to LS) was a Danish political left-wing organization which was founded on November 8, 2009, at its third initial meeting in Horsens.

Instead LS advocates and uses the direct-action-methods of mass anarchism and syndicalism: strikes, blockades, occupations, sabotage, work-to-rule, boycotts, slowdown, demonstrations, etc.

LS consider the revolutionary general strike and the popular insurrection as the ultimate weapons that can end capitalism and statism and bring about a libertarian socialist society.

[19][20] The protests had the effect that speakers from the Social Democrats and SF had to interrupt their speeches ahead of time at the meetings in Copenhagen, Aalborg, Aarhus and other cities.

The Anarkismo-network's European branch has created EuroAnarkismo[31] with the aim of strengthening the international cooperation and the anarchist movement in Europe.
