The Flintstones is an American animated sitcom produced by Hanna-Barbera Productions. The series takes place in a romanticized Stone Age setting and follows the activities of the titular family, the Flintstones, and their next-door neighbors, the Rubbles. It was originally broadcast on ABC from September 30, 1960, to April 1, 1966, and was the first animated series to hold a prime-time slot on television.

The show follows the lives of Fred and Wilma Flintstone and their pet dinosaur Dino, eventually seeing the addition of baby Pebbles. Barney and Betty Rubble are their neighbors and best friends. They adopt a super-strong baby named Bamm-Bamm and acquire a pet hopparoo called Hoppy.

Producers William Hanna and Joseph Barbera, who had earned seven Academy Awards for Tom and Jerry, and their staff faced a challenge in developing a thirty-minute animated program with one storyline that fit the parameters of family-based domestic situation comedy of the era. After considering several settings and selecting the Stone Age, one of several inspirations was The Honeymooners (in itself traceable to The Bickersons and Laurel and Hardy), which Hanna freely praised as one of the finest comedies on television. The show's animation required a balance of visual as well as verbal storytelling that the studio created and others imitated.

The continuing popularity of The Flintstones rests heavily on its juxtaposition of modern everyday concerns in the Stone Age setting. The Flintstones was the most financially successful and longest-running network animated television series for three decades, until The Simpsons surpassed it in 1997. In 2013, TV Guide ranked The Flintstones the second-greatest TV cartoon of all time (after The Simpsons).
