The Lackfi, Laczkfi or Laczkfy (Croatian: Lacković/Laczkovich) was a noble family from Kingdom of Hungary and Croatia, which governed parts of Transylvania (as Count of the Székelys) and held the title of Voivode of Transylvania in the 14th century. The Lackfi family were one of the most prestigious families in 14th-century Kingdom of Hungary during the reign of the Capetian House of Anjou. The family also gave several Bans of Croatia (Slavonia and Dalmatia included) and Bulgaria, and held the titles of Palatine of Hungary and Prince of Zadar, as well as a Viceroy to Kingdom of Naples. After Sigismund's accession to the throne and the Bloody Sabor of Križevci (1397), the family lost all of its political influence and soon became extinct by 1420.
The family started with Lack, Count of the Székelys of the Herman (Hermány) clan which are thought to have sprang from the Raabs family from Raabs an der Thaya in Lower Austria later Lords of Nuremberg. The theory says they arrived in 995 together with Giselle of Bavaria and settled in the southern area of the Pannonian Basin. His descendants took the name of Lackfi which means son of Lack (Laczk). After having lost most of their influence following the Bloody Sabor of Križevci the remaining branch of the family settled on their Croatian estates in Križevci County.
