Although Rousset can be traced back to the Romans, the first written mention comes in a 1050 document, under the name of "Rosselun" or "roscetum rosetum".^[3] In the Middle Ages, a castle as well as a church and chapels were built, as dwellings increased.^[3]

In the 9th century, Rousset belonged to the Abbey of Saint-Victor,^[3] then by 1143 the Knights Templar took over,^[3] followed by the Knights of Malta in 1307.^[3] In the 15th century, it belonged to Guillaume de Littera (1371-1452).^[4]

Under the French Revolution, the castle was destroyed.^[3]

The church was built in 1861.^[3]

It is now home to a semiconductor fab and research center of STMicroelectronics and until 2014 also of another fab of LFoundry [de] (originally set up by Atmel)

• Rousset is twinned with Kirkop in Malta.^[3]
