* ActingForTwo: Ronnie Claire Edwards played both Corabeth and her lookalike sister Orma Lee.
* BizarroEpisode: The episode 'The Changeling' is about a poltergeist invading the Walton home. No other episode features any overt supernatural elements (though 'The Ghost Story' is ambiguous about a Ouija Board) and this is never mentioned again.
* CatchPhrase: Grandma's "Good Lord!"
* FanonDiscontinuity: The episodes in Season 9 where it is revealed that [[spoiler: Curt]] is still alive get this treatment.
* MemeticMutation: "Good night, John Boy."
* NightmareFuel: "The Changeling" episode.
* SeasonalRot: Season 9.
* SignatureScene: An exterior shot of the house as everyone wishes each other a good night, ending with "Good night, John Boy."
* TearJerker: The season 6 episode "Grandma Comes Home" combines this with HarsherInHindsight: It's Grandma Walton's first episode back after Ellen Corby's stroke, but it also ends up being Grandpa's last because Will Geer [[TheCharacterDiedWithHim died during the show's hiatus]]. The season 7 premiere "The Empty Nest" deals not only with the loss of Grandpa, but also Flossie Brimmer (whose actress had also died).
* TheyChangedItNowItSucks: Several fans dislike Season 9, mainly because of the different actor for John-Boy and the episodes that focus on the sons fighting in the war. Also, by this point four of the original cast members had left.
