Citiy of Raška was named  by  Serb medieval state that comprised parts of what is today Serbia, Montenegro, Bosnia and Herzegovina, and southern Dalmatia, being centred in the region of Raška (hence its exonym). The state was formed in ca. 1091 out of a vassal principality of Duklja, a Serb state which had itself emerged from the early medieval Serbian Principality that was centred in Raška until 960, when it was left in obscurity in sources after the Byzantine–Bulgarian wars. Its founder, Vukan, took the title of Grand Prince when his uncle and overlord Bodin ended up in Byzantine prison after decades of revolt. While Duklja was struck with civil wars, Raška continued the fight against the Byzantines. It was ruled by the Vukanović dynasty, who managed to put most of the former Serbian state under their rule, as well as expanding to the south and east. Through diplomatic ties with Hungary it managed to retain its independence past the mid-12th century. After a dynastic civil war in 1166, Stefan Nemanja emerged victorious. Nemanja's son Stefan was crowned king in 1217, while his younger son Rastko (monk Sava) was ordinated the first Archbishop of Serbs in 1219.

The town and municipality bears the name of the historical Raška region. From 1929 to 1941, Raška was part of the Zeta Banovina of the Kingdom of Yugoslavia.

Raska as a settlement was first mentioned in 1835, and the town of Raska was proclaimed at the session of the State Council of the Principality of Serbia on September 6, 1845, at the proposal of politicians and statesman Ilija Garašanin. Prince Aleksandar Karađorđević, by his decision of 17 September 1845, proclaimed the establishment of Raska.

The first urban plan of Raska dates from 1844, which was done by Nikola Alković, which is considered one of the oldest urban plans.

The wars between 1912 and 1918 did not miss Raska. Development in the post-war period was slow. In one period, during the First World War, from October 31 to November 15, 1915, Raska was in some way the capital of Serbia because it was hosted by the King and the then Serbian government. Raska was acquitted on November 27, 1944.

 Today's Raska municipality, as a distinct functional-spatial unit, was formed in 1960
