Giorgi IV Dadiani (Georgian: გიორგი IV დადიანი; died 1715) was Prince of Mingrelia from 1691 to 1704 and from 1710 to 1715. Giorgi's accession to rulership, following his ouster of the First House of Dadiani, inaugurated Mingrelia's second Dadiani dynasty, stemming from the House of Chikovani. Giorgi was also known as Lipartiani (ლიპარტიანი) by virtue of having Salipartiano as a fief from 1682 to 1715. Giorgi was actively involved in a series of civil wars that plagued the western Georgian polities. He was eventually deposed by his own son and placed under house arrest.
