Pietro II Orseolo (died 1009) was the Doge of Venice from 991 to 1009.

He began the period of eastern expansion of Venice that lasted for the better part of 500 years. He secured his influence in the Dalmatian Romanized settlements from the Croats and Narentines, freed Venetia from a 50-year-old taxation to the latter, and started Venetia's expansions by conquering the islands of Lastovo (Lagosta) and Korčula (Curzola) and acquiring Dubrovnik (Ragusa).

In 992 Pietro II Orseolo concluded a treaty with the Byzantine emperor Basil II to transport Byzantine troops in exchange for commercial privileges in Constantinople. His dogaressa was Maria Candiano.

Following repeated complaints by the Dalmatian city-states in 997, the Venetian fleet under Orseolo attacked the Neretvian pirates of Neretvia on Ascension Day in 998. Pietro then took the title of Dux Dalmatianorum (Duke of the Dalmatians), associating it with his son Giovanni Orseolo.

On 9 May 1000 Doge Pietro II decided to finally pacify the Croatians and the Narentines during the last Croatian-Bulgarian wars, protecting Venetian trade colonies and the interests of Romanized Dalmatians. Without difficulties, his fleet of 6 ships scorched the entire eastern half of the Adriatic coast, with only the Neretvians offering resistance. After the Neretvians stole goods and captured 40 tradars from Zadar, the Doge dispatched 10 ships that caught the Neretvians near the island of Kača. He captured them all and brought them triumphantly to Split. There, Neretvian emissaries requested the release of the prisoners. Pietro II agreed provided that the Neretvian Archont himself agreed to bow before him. Moreover, the Neretvians would also have to renounce the old tax that Venetia had to pay since 948, and guarantee safe passage to Venetian ships in the Adriatic.
