Ubayd Allah ibn Abi Bakra (عبيد الله بن أبي بكرة, died c. 698-699 CE) was an Umayyad governor of Sijistan and a military commander.

[1][4] During the early reign of Caliph Abd al-Malik (r. 685–705) Ubayd Allah supported the pro-Umayyad faction in Basra, one of the two principal garrison towns of Iraq, against its ruler at the time Mus'ab ibn al-Zubayr, the representative of his brother, the rival caliph Abd Allah ibn al-Zubayr.

[4] He was reappointed over Sijistan a second time in 697/698 by Abd al-Malik's governor of Iraq and the east, al-Hajjaj ibn Yusuf.

[3] He was succeeded as governor of Sijistan by his son Abu Bardha, who held the post for one or two years and is known to have minted coinage as well.

After some initial successes, he reached an agreement with the Zunbils, who agreed to return the hostages captured from Ubayd Allah and resume paying the tribute at the original rate.
