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).
