This was George Uttley's (Tom Poston) all-time favorite show in the sitcom Newhart (1982). George would often quote Barnaby when faced with a problem and he needed sage advice to solve it.

Buddy Ebsen was 64 years old when the show started.

Shortly after the cancellation of The Beverly Hillbillies (1962), Buddy Ebsen was Quinn Martin's first choice for the lead role in the show, and he accepted it.

The show was intended as a spin-off from another Quinn Martin production, Cannon (1971). Ultimately, they produced three crossover episodes (guest-starring Cannon's William Conrad), including the Barnaby Jones pilot, "Requiem for a Son."

J.R.'s initials stood for Jedidiah Romano.

After production of Barnaby Jones completed, producers were considering a TV-movie crossover between this show and Buddy Ebsen's previous show The Beverly Hillbillies (1962). The story line would open with millionaire Jed Clampett (played by Ebsen) being kidnapped, and Barnaby Jones (also played by Ebsen) hired to locate him. That TV-movie was never produced, although a similar story line was created for the 1993 big screen version of "Hillbillies", with Ebsen returning in a cameo as Barnaby Jones, hired by Miss Hathaway to find the missing Granny.

Barnaby Jones guest stars frequently included children of the regulars. Among them, Buddy's daughter Bonnie Ebson appeared in six episodes, playing a different character every time. Also featured were Lee Meriwether's daughter, Kyle Aletter, and producer Quinn Martin's daughter, Jill Martin.

Barnaby's favorite drink was milk.
