The National Union for Independence-Kanak and Socialist National Liberation Front (French: Union Nationale pour l'Indépendance - Front de Libération Nationale Kanak et Socialiste) is a militant socialist pro-independence alliance of political parties in New Caledonia. It was founded in 1975 at a congress of various political parties, mainly indigenous but also of disgruntled and progressive new-caledonians of European descent.

The FLNKS is composed of Union Caldedonienne (a center-left multi-ethnic party dating back to the early postwar period), the Union Progressiste Melanesienne (a political movement based on the island's west coast and mainly around the village of Poya, where its founder, the late Edmond Nekiriai hails from), the Parti Socialiste Caledonien (a left-wing, mostly european party) and the Parti de Liberation Kank (PALIKA), a more radical party founded by left leaning students that came back from France after the 1968 riots.

In the latest legislative elections of May 9, 2004, it won 13.7% of the popular vote, and 8 out of 54 seats in the Territorial Congress.

Its publishing arm is the associative incorporated society Edipop that runs the radio station Radio Djiido
