Huesca dates from pre-Roman times, and was once known as Bolskan in the ancient Iberian language.
It was once the capital of the Vescetani, in the north of Hispania Tarraconensis, on the road from Tarraco (modern Tarragona) and Ilerda (modern Lleida) to Caesaraugusta (modern Zaragoza).
During Roman times, the city was known as Osca, and was a Roman colony under the rule of Quintus Sertorius, who made Osca his base.
The city minted its own coinage and was the site of a prestigious school founded by Sertorius to educate young Iberians in Latin and Roman customs.
After Sertorius, it is thought that it was renamed Ileoscan (Ἰλεόσκαν) by Strabo.
It appears to have been situated on silver mines.

Eighteenth-century Spanish historian Enrique Flórez has pointed out the impossibility of one city supplying such vast quantities of minted silver as has been recorded by ancient writers under the terms argentum Oscense, signatum Oscense; and is of the opinion that "Oscense" meant "Spanish", being a corruption of "Eus-cara".
 The Romanised city was made a municipium by decree of Augustus in 30 BC.

The Arabs conquered the city in the late 8th century, and the city came to be called Washqah (وشقة in Arabic), falling within the Upper March of the Emirate of Córdoba.
It was ruled by a local governor appointed from Córdoba, but was repeatedly subject to political turmoil, rebellion and assassination as the Banu Qasi, Banu Amrus and Banu al-Tawil clans, as well as the Arista dynasty of Pamplona, struggled for control, autonomy and independence from the Emirate.
In the mid-10th century, Wasqah was transferred to the Banu Tujib, who governed the Upper March from Zaragoza, and it became part of the Taifa of Zaragoza in 1018 when they successfully freed themselves from the disintegrating Caliphate.
In 1094 Sancho Ramirez built the nearby Castle of Montearagón with the intention of laying siege to Wasqah but was killed by a stray arrow as he reached the city's walls.
It was conquered in 1096 by Peter I of Aragon.

In 1354, King Peter IV of Aragon founded the University of Huesca, which initially had a faculty of theology.
The school expanded, but by the end of the 16th century was eclipsed by the University of Zaragoza.
The university was abolished in 1845.

During the Spanish Civil War (1936–39) the "Huesca Front" was the scene of some of the worst fighting between the Republicans and Franco's army.
The city was besieged by the Republicans, George Orwell among them, but didn't fall.
