David Dadiani (Georgian: დავით დადიანი; 23 January 1813 – 30 August 1853), of the House of Dadiani, was Prince of Mingrelia, in western Georgia, from 1846 until his death in 1853. A son of Levan V Dadiani, he became de facto ruler of Mingrelia on his father's retirement in 1840. Like his father, David ruled as an autonomous subject under the protection of the Russian Empire and concurrently held the position of a major-general of the Russian army. David presided over the frequently heavy-handed efforts to modernize Mingrelia's government, economy, and education. The Russian authorities, citing the Mingrelians' discontent with Dadiani's harsh measures, attempted, but failed to bribe him into resigning his office. David died of malaria at the age of 40.
