Captain Mary Oceaneer is a character who originates from Hong Kong DisneySea's Haunted Mansion, Mystic Manor; but who has since appeared as a more pivotal character in different attractions throughout the parks.


Captain Mary Oceaneer was a sea-captain and treasure hunter who was a member of the Society of Explorers and Adventurers and who had an avid love for pirates and their lore.  Mary had a high-end ship known as the "Oceaneer Lab" which made it's maiden voyage on July 30th of 1898. Aboard the vessel, Mary recovered a buried treasure at Castaway Cay.

Mary's first appearance in Mystic Manor

In 1899, Mary attended a S.E.A. meeting at Mystic Point alongside Lord Henry Mystic, his pet monkey AlbertDr. J.L. BateristaProfessor R. Blauerhimmel, Harrison Hightower III and the cursed idol Shiriki Utundu.  During this same year, Mary participated in an expedition along the Orinoco River in South America.

During an unknown year (likely in the early 20th century) Mary and her pet parrot Duncan took her then ship M.S. Salty IV to Blustery Bay on a treasure hunt.  Mary and her ship got caught in a typhoon during this voyage however causing her ship to be wrecked at a place known as Placid Palms (later renamed Typhoon Lagoon) where she and her pet were forced to make their new home.


  • Mary's surname "Oceaneer" is an allusion to her profession's direct involvement with the ocean while her first name Mary is a play on words of her being "merry" and/or a reference to imagineer/Disney concept artist Mary Blaire who created much of the artwork featured in Captain Oceaneer's areas in the Disney Cruise Lines.
  • Despite making her first appearance in Mystic Manor, none of Mary's Disney Park appearances afterwards have been connected to a Haunted Mansion franchise.
