Main characters

Bob Denver as Willy Gilligan

Alan Hale Jr. as Cpt. Jonas Grumby ("The Skipper")

Dawn Wells as Mary Ann Summers

• Willy Gilligan (portrayed by Bob Denver) – The title character of the sitcom. Gilligan is a crewman of the S. S. Minnow who worked for the Skipper. He is well-meaning but bumbling, and he always seems to inadvertently mess up the castaways' escape. He wears a red shirt, light blue pants, and a white sailor's hat. His first name is never mentioned on the show; he is referred to only by his surname of "Gilligan."
• Cpt. Jonas Grumby (portrayed by Alan Hale Jr.) – Referred to on the series only as "The Skipper," he is the captain of the S. S. Minnow. He is portly, leading to numerous fat jokes from Gilligan. Such an instance is when the Professor and Gilligan are helping him into a wetsuit: the Skipper says that he just has big bones, to which Gilligan adds: "and they're covered in big meat." Whenever he gets frustrated with Gilligan, he swats him in the head with his hat.
• Thurston Howell III (portrayed by Jim Backus) – Thurston is a millionaire used to luxurious living and never does any work on the island. The only exception is when the castaways believe that Mr. Howell is broke and make him work. He devises many get-rich-quick schemes on the island. Thurston was originally a multi-billionaire until the stock market crash rendered him a multi-millionaire.
• Eunice "Lovey" Howell (portrayed by Natalie Schafer) – Thurston's wife. She can be more spoiled than Mr. Howell at times, but is always the first to want to try something new. Mr. Howell always calls her "Lovey". Her maiden name is Wentworth.
• Ginger Grant (portrayed by Tina Louise) – A Hollywood movie star. Ginger usually tries to use tricks from the movies she starred in to solve problems causing other castaways to rescue her from any dangers that befall her. She helps Mary Ann with cooking and dishwashing.
• Roy Hinkley, Ph.D. (portrayed by Russell Johnson) – Referred to on the series only as "The Professor," and he was a high school teacher and scout master before being stranded on the island. He has numerous scientific degrees and uses his knowledge to build many things on the island out of available materials. He is the most well-educated of the group and always has a logical answer to everything (although not always correct).
• Mary Ann Summers (portrayed by Dawn Wells) – A farm girl from Winfield, Kansas. Not much is known about her before she gets to the island. She is portrayed as a typical "girl next door" and does most of the laundry and cooking with some help from Ginger. She is famous for her coconut cream pies which usually end up on Gilligan's face. She also appears to have a slight crush on Gilligan.

Recurring characters

• Radio Announcer (voiced by Charles Maxwell) – An announcer on the radio that the castaways own. The castaways would listen to his plot-advancing radio bulletins in many episodes and always with perfect timing to hear the exact news they needed to know.
• Wrongway Feldman (portrayed by Hans Conried) – A fighter pilot from World War I. He was stuck on the island when he tried to fly around the world in The Spirit of the Bronx. He leaves at the end of the episode, but returns later saying he will stay on the island. However, he leaves again but he crashes and never appears again. The castaways get a message from him saying he "crashed on a strange island" which appears to be Hawaii.
• Dr. Boris Balinkoff (portrayed by Vito Scotti) – A mad scientist who appears twice. For his first appearance, he takes the castaways to his secret lair on another island. In the end, the castaways escape. The second time, he uses mind-control rings to get the castaways to rob Fort Knox. He then flees when they attack him with coconuts and is never seen by them again. He owns a pet monkey named Igor.
• Japanese Sailor (portrayed by Vito Scotti) – Appeared in two episodes. For his first appearance, he locks everybody on the island up except Gilligan and Skipper. In his second appearance, he appears in a flashback of events that never happened.
• The Gorilla (performed by Janos Prohaska) – The only animal antagonist on the island, causes mayhem and mischief. In the episode '"Diamonds Are an Ape's Best Friend", he kidnaps Mrs. Howell because her perfume acted as a pheromone. In the episode "Chain of Command", he disciplines Gilligan to be a better leader. In the episode "Forward March", he shells the castaways with hand grenades after finding WWII weapons in a cave. In the episode "Our Vines Have Tender Apes", the Gorilla is replaced as a large orangutan. Janos Prohaska also performed Gladys the chimpanzee in the episode "Beauty Is as Beauty Does".

Guests on Gilligan's Island

In some episodes, there are different people who appear on Gilligan's Island that are either visitors or have been on the unexplored parts of the island.

• The Mosquitoes – A rock/pop group who came to the island to escape all their fans. A pastiche of The Beatles, they were annoyed into leaving by the castaways, who eventually got them to leave by the girls forming the musical group "The Honeybees". The Mosquitoes left, leaving behind one of their records, called "The Mosquitoes at Carnegie Hall". Their names are Bingo, Bango, Bongo, and Irving.
• Erika Tiffany-Smith (portrayed by Zsa Zsa Gabor) – Appeared in the season two episode "Erika Tiffany-Smith to the Rescue". Erika is a rich socialite and is a rival to Mrs. Howell. However, Mr. Howell takes a liking to Erika when she lets word out that she wants to buy the island; and, as usual, Mr. Howell takes all money offers. Erika falls in love with the Professor, ignores Mary Ann's sweetness and the Skipper's advances of romance, and treats Gilligan (like everyone else) as a butler. Ginger adores Erika because of her owning several movie studios; however, Ginger doesn't appear on screen with Erika at all. Erika leaves claiming to return and rescue the castaways and buy the island. Like other visitors, she never returns. She is heard on the radio at the end of the episode saying she doesn't know the coordinates of the island.
• Harold Hecuba (portrayed by Phil Silvers) – Season 3, episode 4 was "The Producer" (airdate October 3, 1966). Obnoxious, overbearing, and smarmy Hollywood producer Harold Hecuba crash-lands on the island. When Ginger's acting fails to impress him, the castaways attempt to woo Hecuba with their collective talent in hopes of enticing him to rescue them. They put on an original play: A musical version of Hamlet consisting of songs sung to the instrumental melodies of popular arias from the operas Carmen and The Tales of Hoffmann (on records owned by Mr. and Mrs. Howell which were inexplicably taken aboard the Minnow and managed to survive the shipwreck). However, true to form as both guest to the island and conniving producer stereotype, Harold Hecuba sneaks back alone to civilization in the night. The castaways soon hear of his new hit smashTemplate:Mdashba musical version of Hamlet.
• Jungle Boy (portrayed by Kurt Russell) – A feral child who is found on the island in the first season episode "Gilligan Meets Jungle Boy" where all he can do is make bird noises and copy certain words. How he got on the island and how he was raised was not revealed in the episode.
