Bal'arab bin Himyar (died 1749) was one of the rival Imams during the civil wars in Oman in the final years of the Yaruba dynasty. He was elected Imam in 1728, holding power in the interior of Oman while his cousin, Saif bin Sultan II, held power on the coast. In 1737 he renounced his claim after being defeated by Saif's Persian allies. He was again elected Imam in 1743 during another Persian invasion, and again held power in the interior while Ahmad bin Said al-Busaidi was recognized as ruler by the coastal people. He died in battle against Ahmad bin Said in 1749. Ahmad became the undisputed ruler of the country.
