Agnello Participazio (Latin: Agnellus Particiacus) was the tenth traditional and eighth (historical) doge of the Duchy of Venetia from 811 to 827. He was born to a rich merchant family from Heraclea and was one of the earliest settlers in the Rivoalto group of islands. His family had provided a number of tribuni militum of Rivoalto. He owned property near the Church of Santi Apostoli.[1] A building in the nearby Campiello del Cason was the residence of the tribunes.[2] Agnello was married to the dogaressa Elena.[3]

The name Agnello appeared in the earliest documents (819 and 820) and in John the Deacon's chronicle Historia Veneticorum. It appeared as Angelo in a document datable to 1023.[4] The surname is attested only later, in John the Deacon's chronicle, who attributed it only to Orso II Participazio (911-932). Its attribution to the whole household and to the prior Participazio doges (Agnello Giustiniano (827–829), Giovanni I (829–836), Orso I (864–881) and Giovanni II (881–887) was established by 19th century scholars.

According to some historians Agnello was elected,[6][7] while others say that he was appointed by Arsaphios, a Byzantine envoy.[8][5]
