    The Southern Transitional Council conflict was a sub-conflict of the Yemeni Civil War, between the separatist Southern Transitional Council (STC) and other factions, mainly the internationally-backed government in Yemen. The STC was supported by the United Arab Emirates, despite the UAE being a member of the Saudi Arabian-led coalition working to support the Yemeni government.

    In 2022, the STC became part of the newly founded Presidential Leadership Council (PLC). In December 2025, the STC launched an offensive claiming much of South Yemen. STC soon thereafter proclaimed a two-year-long process for self-determination. After the Saudi-led coalition launched a counter-offensive, the STC announced its dissolution of 9 January 2026 ending the conflict.
