This is a list of non-communist states that self-identify as socialist states. That means this list includes African socialist states, Arab socialist states, Ba'athist states, and other unique socialist state formations.
These are territories that have claimed autonomy and declared themselves as socialist under some interpretation of the term. While these regions have created stable institutions of governance that have existed for a considerable period of time, they are not widely recognized as autonomous by the international community and officially are parts of other sovereign states under international law.
These are short-lived political entities that emerged during wars, revolutions, or unrest and declared themselves socialist under some interpretation of the term, but which did not survive long enough to create a stable government or achieve international recognition.
These are short-lived political entities which are usually established locally during a revolution, uprisings or by partisans. While some might be founded by communists as soviet republics they do not fall under actually existing socialism and usually do not have a clearly defined claimed territory nor a proper constitution.
