Imam Azzan bin Qais (Arabic: الإمام عزان بن قيس) was the Imam of Oman between 1868 and 1870. He deposed his distant relative Sayyid Salim bin Thuwaini and ruled according to religious law. He also opposed the Saudi interference in the Buraimi Oasis. He fought against Salim's uncle, Sayyid Turki bin Said at the Battle of Dhank, before being killed in battle at Muttrah in 1871.
