Gojslav (died 1020) was a monarch who co-ruled theKingdom of Croatia with his brotherKrešimir III from 1000 to his death in 1020. He was the youngest son of the former Croatian KingStjepan Držislav and a member of royalHouse of Trpimirović.

After Croatia's King Stjepan Držislav died in 997, his brotherSvetoslav Suronja became King of Croatia. Together with his brotherKrešimir III he revolted againstSvetoslav Suronja. Because Croatian kings had been allies of theByzantine Empire during war with theFirst Bulgarian Empire, the rebels requested Bulgarian help. This resulted in the Bulgarian invasion of 998, during which EmperorSamuil took Croatian Dalmatia and great parts ofBosnia.^[1] After the war, the Bulgarian emperor gave this territory to Gojslav andKrešimir III. During the last two years (999–1000) of the Croatian civil war the brothers, with Bulgarian help, defeatedSvetoslav Suronja, who went into exile in Venice in 1000. Thereafter, the Venetian Doge,Pietro II Orseolo, successfully intervened in Dalmatia, winning control of theDalmatian cities.

Gojslav andKrešimir III spent their reign attempting to restore rule over the Dalmatian cities. This brought upon them a renewed conflict with Croatia's former protector, theRepublic of Venice, in 1018. Peace was concluded upon the diplomatic intervention of Byzantine EmperorBasil II which confirmed Gojslav andKrešimir III, as Byzantine vassals and kings of Croatia after the defeat of the First Bulgarian Empire. Gojslav died in 1020.
