Bediani (Georgian: ბედიანი) was a medieval title, or a territorial epithet, of the Dadiani, the ruling family of Mingrelia in western Georgia, derived from the canton of Bedia, in Abkhazia, and in use from the end of the 12th century into the 15th. Bediani was occasionally used as a praenomen. The extent of the fief of Bedia is difficult to define; by the latter half of the 17th century, the Shervashidze of Abkhazia had supplanted the Dadiani in that area.
