Tiger Shark is a Batman villain from Earth-Two. He was originally a famed oceanographer named Dr. Gaige, who eventually turned to crime. The character was later remodeled in the Modern Age Detective Comics as a pirate smuggler who worked out of Gotham City, with a base in international waters. Despite staying blindfolded, he was an expert tactician with very expensive tastes.

Tiger Shark was created by Bill Finger and Dick Sprang, first appearing in Detective Comics #147 (1949).
