The 1527 election in Cetin (Croatian: Cetinski / Cetingradski sabor, meaning Parliament on Cetin(grad) or Parliament of Cetin(grad), or Cetinski / Cetingradski izbor) was an assembly of the Croatian Parliament in the Cetin Castle in 1527. It followed a succession crisis in the Kingdom of Hungary caused by the death of Louis II, and which resulted in the Kingdom of Croatia joining the Habsburg monarchy. The charter electing the Habsburg Archduke of Austria Ferdinand I as King of Croatia was confirmed with the seals of six Croatian nobles.
