The Arab conquest of Pars took place from 638/9 to 650/1, and ended with subjugation of the Sasanian province of Pars, also known as Fars or Persis, to the Rashidun Caliphate under Umar.

The Arab invasion of Sasanian Pars took place in two phases. An initial Bahraini naval expedition in 638 ended in failure. After a change in Bahrain's governor, that unsuccessful campaign was followed with a second campaign conducted in 643 by a combined force of Arab tribesmen from Bahrain and Oman under the leadership of Uthman ibn Abi al-As al-Thaqafi that ultimately overran the province.^[1]

The Sasanian emperor Yazdegerd III, who had travelled to Pars to command the defense against the Arabs, was forced to flee to Kirman. This ended Sasanian control or the territory, though its population would later rebel several times against Arab rule.^[2]
