Thecorporatecounsel.net, accessed March 31, 2011</ref> Below are those who have made more than one appearance:

* Mr. Nate Slate – Fred’s hot-tempered boss at the gravel pit, who fires him on several occasions only to give him his job back (and inevitably grant him a raise every time he requests one). A running gag is his ever-changing first name, which has been revealed to be Sylvester, Seymour, Nate, Oscar, and George throughout the series. In the episode "The Long, Long, Long Weekend", he is shown to be the founder of "Slate Rock and Gravel Company", which is still in business two million years later and operated by his descendant, "George Slate the Eighty-thousandth". In early episodes, the more recognized "Mr. Slate" character was known as "Mr. Rockhead" and was a supervisor of Fred, while Mr. Slate was a short character. Over time, the two switched identities and the shorter version of Mr. Slate was phased out.
* Arnold – The Flintstones' [[paperboy]], whom Fred despises mainly because Arnold is frequently able to best and outsmart him and because he often throws the newspaper in his face. Arnold's parents are mentioned in the series, but his mother Doris, who is a friend of Wilma and Betty as shown in the episode "The Little Stranger", is referenced but never physically appears. Arnold's father appears in the episode "Take Me Out to the Ball Game", though his name is never mentioned.
* Joe Rockhead – A mutual friend of Fred and Barney, Fred usually mentions doing something with Joe when Fred and Barney have a falling out. Joe was, at some point, the [[fire chief]] of the Bedrock Volunteer Fire Department, as shown in the episode "Arthur Quarry's Dance Class". His appearance varied throughout the run of the series, but his appearance in the episode "The Picnic" was his most common appearance.
* Sam Slagheap – The [[Grand Poobah]] of the Water Buffalo Lodge.
* The Hatrocks – A family of [[Hillbilly|hillbillies]], who feuded with the Flintstones' Arkanstone branch similarly to the [[Hatfield–McCoy feud]]. Fred and Barney reignite a feud with them in "The Bedrock Hillbillies", when Fred inherits San Cemente from his late great-great-uncle Zeke Flintstone and they fight over who made Zeke's portrait. The Hatrocks later return in "The Hatrocks and the Gruesomes", where they bunk with the Flintstones during their trip to Bedrock World's Fair and their antics start to annoy them as they guilt-trip Fred into extending their stay. It is also revealed that they dislike bug music, and the Flintstones, the Rubbles, and the Gruesomes are able to drive them away by performing the Four Insects song "She Said Yeah Yeah Yeah".{{efn|The name "The Four Insects" is clearly a play on the British band "[[The Beatles]]", then at the height of their fame. The song "She Said Yeah Yeah Yeah" is a play on The Beatles' "[[She Loves You]]".}} After learning that the Bedrock World's Fair would feature the Four Insects performing, they fled back to Arkanstone.
** Jethro Hatrock – The patriarch of the Hatrock Family. He had brown hair in "The Hatrocks and the Flintstones" and taupe-gray hair in "The Hatrocks and the Gruesomes".
** Gravella Hatrock – Jethro's wife.
** Zack Hatrock – Jethro and Gravella's oldest son.
** Slab Hatrock – The youngest son of Jethro and Gravella.
** Granny Hatrock – The mother of Jethro and grandmother of Zack and Slab.
** Benji Hatrock – Jethro's son-in-law.
** Percy – The Hatrock's pet dogasaurus.
* The Gruesomes – A creepy but friendly family, who move in next door to the Flintstones in later seasons.
** Weirdly Gruesome – The patriarch of the Gruesome family, who works as a reality-show host.
** Creepella Gruesome – Weirdly's tall wife.
** Goblin "Gobby" Gruesome – Weirdly and Creepella's son.
** Uncle Ghastly – The uncle of Gobby from Creepella's side of the family, who is mostly shown as a large furry hand with claws emerging from a door, a well, or a wall. His shadow was also seen in their debut episode. He wasn't named until his second appearance, which is also the only time he is heard speaking, as he is heard laughing from a well.
** Occy – The Gruesome family's pet giant octopus.
** Schneider – Gobby's pet giant spider.
* [[The Great Gazoo]] – An [[Extraterrestrial life|alien]] from the planet Zetox, who was exiled to Earth and appears in the final season. He helps Fred and Barney with his reality-warping abilities, often against their will. He is actually from the future and is quite dismayed after realizing he has been sent back to "the Stone Age". He can be seen only by Fred, Barney, Pebbles, Bamm-Bamm, other small children, Dino, and Hoppy.
