David Dadiani (Georgian: ????? ???????; 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 of the Russian Empire and served as 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.
