Sarakhs (Persian: سرخس) is a city in the Central District of Sarakhs County, Razavi Khorasan province, Iran, serving as capital of both the county and the district. Sarakhs was once a stopping point along the Silk Road, and in its 11th century heyday had many libraries. Much of the original city site is now just across the border at Serakhs in Turkmenistan.
