The Osaarian merchant fleet was an organization of Osaarians. By 2153, the Osaarian merchant fleet was known by the Vulcan High Command as a large group. Sub-Commander T'Pol told Captain Jonathan Archer about the Osaarian merchant fleet after Enterprise NX-01, a starship Archer and T'Pol were meanwhile serving aboard, was raided by Osaarian pirates from an Osaarian merchant ship.
