Filocalo Navigajoso (died 1214) was a Venetian (or possibly of mixed Greek and Venetian descent[1]) nobleman and first Latin ruler of the island of Lemnos (known as Stalimene in Italian) in Greece.
Following the Fourth Crusade (1203–1204), most of the Aegean islands were apportioned to the Republic of Venice in the partition of the Byzantine Empire.
Various Venetian nobles settled there and claimed the rule of these islands as fief-holders and vassals of the Latin Emperor at Constantinople.
Filocalo received the rule of Lemnos and the title, borrowed from Byzantine court titulature, of megadux of the Latin Empire.
He ruled the island from the fortress of Kastro or Palaiokastro (modern Myrina) until his death in 1214.
