"Baron" Mikel Scicluna (July 29, 1929 – March 20, 2010) was a Maltese-born professional wrestler who gained his fame during the 1960s and 1970s.

Scicluna started wrestling during the 1950s, and used the name Mike Valentino early in his career. Scicluna worked primarily in Canada until 1965, when he ventured to the World Wide Wrestling Federation (WWWF), now known as WWE, using his most famous moniker "Baron" Mikel Scicluna.

Scicluna was famous for entering the ring with a royal blue cape over his shoulders, indicating that he was of Maltese royal descent. Scicluna was also known for being a master of the "foreign object", mainly utilizing a roll of coins to bash opponents out of sight of the referee. He enjoyed success as a tag team wrestler, winning the WWWF United States Tag Team Championship with Smasher Sloan on September 22, 1966 in Washington, D.C. (though they eventually lost the belts in the same city to Spiros Arion and Antonio Pugliese), then the WWWF World Tag Team Championship with King Curtis Iaukea on February 1, 1972 in Philadelphia.
