The Republic of Yemen (Arabic: الجمهورية اليمنية‎ al-Jumhūrīyah al-Yamanīyah), commonly known as Yemen ⁱ/ˈjɛmən/ (Arabic: اليَمَن‎ al-Yaman), is a country located in Western Asia, occupying the southwestern to southern end of the Arabian Peninsula. It is bordered by Saudi Arabia to the north, the Red Sea to the west, and Oman to the east. Yemen is considered one of the poorest countries in the Arab world. Its capital and largest city is Sana'a. Yemen's territory includes over 200 islands, the largest of which is Socotra, about 415 km (258 mi) to the south of mainland Yemen, off the coast of Somalia. It is the only state in the Arabian Peninsula to have a purely republican form of government. Approximately 53% of Yemenis are Sunnis, while 45% are Zaydi Shias.

One etymology derives Yemen from yamin, meaning "on the right side", as the south is on the right when facing the sunrise. Another derives Yemen from yumn, meaning "felicity", as the region is fertile. The Romans called it Arabia Felix (Happy Arabia) as opposed to Arabia Deserta (Deserted Arabia), which was their term for northern Arabia.
