Marco Venier, Lord of Cerigo

Marco Venier (died 1311) was a Venetian noble of the Venier family and Lord of Cerigo, the island of Kythera off the southern Greek coast. He was born to a daughter of Nikolaos Evdaimogiannis, the Greek lord of Kythera.

In 1310 the Venetians and the Venier clan retook the island, which Byzantium had held since 1269. Marco died in 1311, and his son Pietro Venier continued the line of Cerigo governors.
