Jonathan Quayle Higgins III, was a character in the 1980s television series, Magnum P.I. portrayed by actor John Hillerman. Higgins is the Majordomo for Robin Masters' beachfront estate on Oahu, which is commonly referred to as Robin's Nest.

After Orson Welles (who voiced Robin Masters) died, Thomas Magnum, a private investigator/security guard for Robin's Nest, began thinking Higgins was Robin Masters. It later became a running gag in the series after Thomas told his friends Theodore "T.C." Calvin, and Orville "Rick" Wright about his idea.

Known facts about Higgins:

• He was once a Sergeant Major in the British Army.
• He was present at the bridging of the River Kwai during WWII, which he claims was "nothing like the movie".

He is fond of Byron and Shelley, which suggests a hidden romantic streak.

Higgins's trademark epithet is the slowly building "Oh...my...GOD!"

Higgins is loosely based on James Bond creator Ian Fleming:

• Both were born into distinguished families of Scottish descent
• Both left Sandhurst, the British officers academy, before graduation
• Both served in the British military during World War II with careers focused on intelligence and special operations
• Both retired to tropical estates after retiring from military service
• Both (if rumors are to be believed) wrote a series of lurid adventure novels loosely based on their own experiences

In addition, in 1946 Higgins refused a direct order to fire on Jewish refugees trying to reach Palestine. This episode ("Torah, Torah, Torah" from season 5) resembles an experience of Patrick Dalzel-Job, reportedly one of the inspirations for James Bond, who refused an order to stop evacuation of Norwegian civilians as that country was being overtaken by the German army near the beginning of WWII.
