The name of the town is derived from its earlier Ottoman-era name Hasköy, which is a hybrid Arabic-Turkish compound meaning "special village" (Turkish has "special" via Arabic خَاصّ + Turkish köy "village"). It was so named after it became the centre of an Ottoman administrative district in the region. The ancient Thracian name of the settlement was Marsa, by which it was known until as late as 1782. By 1830, it was known by its Turkish name, Hasköy. The Bulgarian (and common Slavic) placename suffix "-ovo" replaced the Turkish "köy" after the city switched to Bulgarian from Ottoman rule.
According to archeologists, the area of Haskovo was originally settled about seven thousand years ago. In and around Haskovo, evidence has been preserved that confirms its long history during the prehistoric, Thracian, Greek, Roman, and Byzantine periods. In the 9th century – during the First Bulgarian Empire – a fortress was built in Haskovo that soon was transformed into a town.
