The Kačić family (Croatian: Kačići, Hungarian: Kacsics, Latin: Cacich) was one of the most influential Croatian noble families, and was one of the Croatian "twelve noble tribes" described in the Pacta conventa and Supetar Cartulary. The historical sources refer to members of this family as nobles in the area of the Luka županija in the Zadar-Biograd hinterland (12th–16th centuries), as the lords (knezes) of Omiš (12th and 13th centuries), and as the lords of the Makarska Riviera (15th and 16th centuries). Another prominent branch of the family, Kacsics, was part of the Hungarian nobility and from it branched many families including Szécsényi.
