The "Sko Phylum" is a group of languages spoken mainly along the coast of Sandaun Province in Papua New Guinea, with a few being inland from this area and at least one just across the border in the Indonesian Province of Papua (formerly known as Irian Jaya---further names changes to this region are in the pipeline).

Some of the members of the Sko phylum are:

  • Skou
  • Wutung
  • Vanimo
  • Krisa
