This is a list of currently active separatist movements in Oceania. Separatism includes autonomism and secessionism.

Criteria

What is and is not considered an autonomist or secessionist movement is sometimes contentious. Entries on this list must meet three criteria:

1. They are active movements with active members.
2. They are seeking greater autonomy or self-determination for a geographic region (as opposed to personal autonomy).
3. They are citizens/people of the conflict area and do not come from another country.

Under each region listed is one or more of the following:

• De facto state (de facto entity): for unrecognized regions with de facto autonomy.
• Proposed state: proposed name for a seceding sovereign state.
• Proposed autonomous area: for movements towards greater autonomy for an area but not outright secession.
  • De facto autonomous government: for governments with de facto autonomous control over a region.
  • Government-in-exile: for a government based outside of the region in question, with or without control.
  • Political party (or parties): for political parties involved in a political system to push for autonomy or secession.
  • Militant organisation(s): for armed organisations.
  • Advocacy group(s): for non-belligerent, non-politically participatory entities.
  • Ethnic/ethno-religious/racial/regional/religious group(s).
