Socotra, locally known as Saqatri, is a Yemeni island in the Indian Ocean. Situated between the Guardafui Channel and the Arabian Sea, it lies near major shipping routes. Socotra is the largest of the six islands in the Socotra archipelago as it comprises around 95% of the landmass of the archipelago. It lies 380 kilometres (205 nautical miles) south of the Arabian Peninsula and 232 km (125 nmi) east of the Horn of Africa. The inhabitants of the island are called Socotrans, and they speak Arabic and Soqotri.

Socotra is home to a high number of unique species that are endemic to it. Up to a third of its plant life is unique. Due to the island's unusual geography, it has been described as "the most alien-looking place on Earth". The island measures 132 km (82 mi) in length and 42 km (26 mi) across at its widest. In 2008, Socotra was recognised as a UNESCO World Heritage Site.

The island is under the control of the Southern Transitional Council (STC), a United Arab Emirates-backed, pro-Presidential Leadership Council (PLC), "secessionist" faction in Yemen's ongoing civil war. The STC seized control of the island following a coup in 2020, ousting the local authorities and establishing its own governance.
