Vladislav[1] or Ladislas (Latin: Ladasclavus; 821) was the Duke of Croatia. In sources he is mentioned as the Duke of Dalmatia and Liburnia (dux Dalmatiae atque Liburnae), having succeeded his uncle Borna, a Frankish vassal. He is mentioned only in the 9th-century Royal Frankish Annals, regarding year 821. Borna had died between January and October 821, during a war against Frankish rebel Ljudevit, Duke of Pannonian Croatia. Borna's nephew (by his sister) Vladislav succeeded him, by the people's will and emperor's approval. Vladislav ruled from Nin as a loyal vassal of the Frankish Emperor Lothair I. In historiography, his realm has been referred to as Dalmatian Croatia or Littoral Croatia, where he was succeeded by Duke Mislav.
