Ocean Master is a supervillain appearing in American comic books published by DC Comics. The character was created by Bob Haney and Nick Cardy and debuted in Aquaman #29 (September 1966). One of Aquaman's most recognized adversaries who constantly conspires to usurp his position as the ruling monarch of Atlantis, the character has been subjected to numerous revisions over the years; The original version of the character was Orm Curry Marius, Aquaman's wayward, human half-brother envious of his sibling's superhuman powers and status as a hero. Becoming an international marine criminal, he takes the name Orm Marius and Ocean Master. Following Crisis on Infinite Earths, the character is depicted as half homo magi and of Inuit origin, his brotherhood with Aquaman connected through Atlan, their shared father.

He is revised once more after The New 52 as a royal Atlantean, son of Queen Atlanna and King Orvax Marius, half-brother of Tula, and a descendant of Atlan and Arion. While he exhibits xenophobic views towards humans and a desire to punish them for their role in marine pollution, he is inherently less malicious as his motivations are more complex in nature, making him both a supervillain and anti-hero. While a benevolent ruler at a young age following the apparent deaths of Orvax and Atlanna, he is ousted and exiled by Aquaman due to believing him a tyrant and Orm's attack on the United States. Embittered, he typically serves as an antagonistic force against Aquaman and his allies as he seeks to restore his status as king, though he is also a reluctant ally at times.

Ocean Master has been adapted from the comics into various forms of media.The character appeared in the DC Extended Universe films Aquaman (2018) and Aquaman and the Lost Kingdom (2023), portrayed by Patrick Wilson. Richard Green, Wallace Langham, Dana Snyder, and Sam Witwer have provided the character's voice in animation.
