Saudi Arabia and Yemen relations refers to the current and historical relationship between Saudi Arabia and Yemen. The two countries at one time did enjoy good relations and closely cooperated in military, economic and cultural issues. Now because of the ongoing Yemeni Civil War and the realignments of power in the Middle East with the emergence of al-Qaeda and the radicalization of some factions of Islam, Saudi Arabia has led a military intervention into Yemen, alongside a nine-member coalition, backed logistically by the United States, using airstrikes inside of Yemen and commencing a naval and aerial blockade beginning March 26, 2015, in order to support the current government of Abd Rabbuh Mansur Hadi in the war against the Houthis.

Modern Saudi-Yemeni relations began in 1803 with an attack by Saudi forces of the territory of Zaydi Imamate with the help of some local Yemeni tribes.

In September 2003, in an effort by the Saudi government to control incursions by Yemenis into Saudi Arabia and slow terrorist actions, the Saudis began construction of a wall of cement-filled pipeline, 10 feet (3 meters) in diameter along its border with Yemen. Following, complaints by the Yemeni government to the Saudis that construction of the wall violated a year 2000 treaty between the two nations, the Saudis stopped work on the wall in February 2004. But by that time, 47 miles (75 kilometers) of cement-filled barrier, of the 1,100 mile (1800 kilometer) border had been erected.
