*Elizabeth Jean "Betty" Rubble (née McBricker/O'Shale) is a fictional character in the television animated series The Flintstones and its spin-offs and live-action motion pictures. She speaks in a Midwestern with a Midwestern accent.

She is the beautiful and very attractive wife of caveman Barney Rubble, the adoptive mother of Bamm-Bamm Rubble, the niece, goddaughter and daugher-in-law of Pebbles Flintstone and the grandmother of Chip and Roxy. Her best friend is her next-door neighbor Wilma Flintstone.

Betty's personality was based on that of Trixie Norton, wife of Ed Norton on the 1950s television series The Honeymooners; each of the four of the series' principal adult characters is an analogue of a Honeymooners character. Much like Trixie spent a lot of her time socializing with Alice Kramden, Betty mostly spends a lot of her time socializing with WIlma, and the two will often end up working together to bail their husbands out of whatever scheme of Fred's has landed them in trouble, sometimes scheming with each other.

Betty can be considered the least developed character in the show, as she is rarely seen not following the lead of either Barney or Wilma, the latter of whom she often seems merely an echo of, generally. In spite of this, Betty is shown to have a distinctly emotional marriage with Barney, which more often included pet names and a more obvious affection, as opposed to the more dynamic and energetic interaction between Fred and Wilma.

This lack of protagonism (almost as background-set as supporting characters such as Pebbles, Bamm-Bamm, or Dino, except for her more continuous presence) makes Betty less of a protagonist as is implied by the general concept of the show. In addition to her attractiveness and beauty, Betty can also be quite emotional.

The occasions when Betty leads the action are extremely scarce: one episode centers around her working undercover as a gentle old lady who uses her to pass "counterfeit" money to buy a present for Barney, and on another occasion the plot for her and Wilma was led by her suspicions of Barney being involved with another woman (which turns out to be Fred in a disguise contrived in order to attend a ball game free of charge).

Betty, much like Wilma, also enjoys volunteering for various charitable/women's organizations in Bedrock, shopping, and (occasionally) getting to meet the celebrities of their world, including Stony Curtis, Cary Granite and Ann-Margrock.

When Bamm-Bamm was a teenager, Betty gained employment as a reporter for one of Bedrock's newspapers (or, more accurately, news-slabs), the Daily Granite (presumably a parody of the Daily Planet of Superman fame), under the editorial guidance of Lou Granite. While employed there, she shared various adventures with prehistoric superhero Captain Caveman, who (in a secret identity) also works for the newspaper.

Later still, after Bamm-Bamm grew up and left home in I Yabba-Dabba Do! and Hollyrock-a-Bye Baby, Betty started a successful catering business, "Bone-Appetite" with her partner Wilma.*
