You dream about goin' up there,
But that is a big mistake!

- In The Wizard of Oz, Dorothy wanted to go somewhere "Over The Rainbow".
- Spoofed in the satire "Water". Michael Caine is the governor of this minor British colony in the Caribbean, and has just received word that the suits back in London are shutting down the colony and shipping the natives off elsewhere. Caine is griping that he's the only one who seems to be angry about this. "I suppose they all want to go where the grass is greener." "They'll find it jolly expensive!" (Caine and his companion are smoking the local dope at the time).
- In Over the Hedge, one of the porcupines compares grass stuck in his quills to the grass in the subdivision, and declares that it actually is greener on the other side.

- In Song of the Lioness, Alanna feels stifled by Tortall's rigid view of gender (rightly so, mind) and goes traveling abroad after King Roald pardons her for her Sweet Polly Oliver deception. When she meets the ex-princess of Sarain, though, she's informed that the consensus among their nobility was that she ought to have been put to death for it.
- This is a plot point in "The Scrambled States of America." Kansas is sick of being stuck in the middle of the country and never meeting any new states, so he decides to have a party and invite all the other states. At the party, the states all decide to switch places. After the states switch places and a few days pass, the states realize they weren't as happy as they thought, so they all go back to their original places.

- Hair: Manchester, England, England, across the Atlantic sea...
- A variation: in The Legend of Zelda: Link's Awakening, even though Koholint Island seems like a perfectly fine place to live and nobody else (besides the hero) ever thinks of leaving, Marin wishes to leave and travel the world like a seagull. Even though the island turns out to be All Just a Dream, if you never die in a run of the game it's shown that she gets her wish.
- What drove Ganon into wanting to get his hands on the three Triforce parts in The Legend of Zelda: The Wind Waker was that he envied the winds that blew on the lush green landscape of Hyrule while his country suffered constantly punishing winds that brought only death.
- Well, not really that he wanted to go to a different country or anything, but...Roxas from Kingdom Hearts 2 became jealous of the visions he had of Sora and his friends. To the point where he actually betrayed and left Organization XIII because he wanted friends and love so badly. The result? He gets tricked by DiZ into merging with Sora. Not quite what he wanted.
- Conkers Bad Fur Day: Conker realizes only after becoming rich and powerful like he always wanted to be that he had everything he wanted all along. Only by then, it was too late.
Conker: It's true what they say, the grass is always greener. And you don't really know what it is you have, until it's gone...
- Team Fortress 2 is the ultimate example of this. 360 players are always complaining that their version never gets any updates like the PC version. PC players are always complain that their version is getting updated, screaming They Changed It, Now It Sucks to the point of having an aneurysm towards everything from a class update to more hats to a small tweak in the netcode. A fair number of players have likely switched sides by now.

- The theme song to As Told by Ginger starts off with "Someone once told the grass is much greener, on the other side, well I took a visit and it's possible I missed it. It looks so different and exactly the same..." The episode "T.G.I.F" even had it as a theme when Ginger stayed over with the posh Gripling Family
- Truth in Television, the classic immigrant story.
- And not just immigrants from one country to another; it's a significant reason for people to move around within a country, too. (having found work elsewhere or going off to school are probably the only more common reasons)
