"Elvis" sounds a lot like "elvish" and looks a lot like "elves", making for a comedically useful stock pun.
The incongruity between the decidedly ethereal and long-lived elves and the earthy and very much mortal and hedonistic Elvis Presley arguably just makes it funnier. Of course, some versions of elves are earthy and hedonistic, in which case it makes an awful lot of sense. And sometimes this is all an act designed to let them steal human children, which just proves the Moral Guardians were right about that hip-thrusting Lothario the whole time.
Then again, sometimes there's no significance to it at all, it's just funny.
For some reason, no one ever makes these jokes about Elvis Costello. Perhaps it's because he doesn't have Presley's far more bitter, cynical sense of humor.
- An advert for Yellow Pages had a man at a fancy dress party dressed as an elf, surrounded by other people dressed as Elvis. He mentions that "[his] invitation definitely said elves, OK?"
- A UK Christmas card has a queue of Elvis impersonators outside Santa's workshop, while he says to Rudolph "What did you write on the want ad, again?"
- ElfQuest included one reference to "Elfis" at some point in a parody version of itself.
- The Elvis Impersonator Spellvis from Gold Digger isn't an elf, but his music is Supernaturally Delicious and Nutritious to women.
- In Teenage Mutant Ninja Turtles Adventures the Neutrinos from Dimension X are Space Elves and Greaser Delinquents with a love for Doo Wop, Jive Talk, and hot-rodded flying cars.
- In the Lord of the Rings Chilean parody "El Señor de los Ladrillos," the Elves became "the Elvis".
- In The Silmarillion fan fiction, the two greatest Elven musicians, Daeron and Maglor, are still assumed to be in the Hither Lands, and often presented as rock musicians. Though usually they aren't associated with any real-life musician (and if they are, it will be someone more recent than Elvis). For some reason they (especially Maglor) are usually depicted as penniless street musicians or otherwise total unknowns. In the original text elves are said to be able to essentially make multimedia presentations with their voices alone, because their powerful souls and minds are more closely aligned. This is sometimes depicted in the fan stories and sometimes ignored.
- One of the earliest examples is Emma Bull's War for the Oaks, where the rock band has Elvish lead guitar and bass players, and a faerie roadie.
- Discworld: Multiple:
- In Soul Music, everyone keeps asking Buddy (a parody of every dead rock star, ever, but especially Buddy Holly as, you know, Buddy's real name "Imp y Celyn" translates as "Bud of the Holly") if he's elvish. (Which is worrisome for Buddy in certain kinds of company, because dwarves and trolls have a standing blood feud against elves.) At the end of the book, after he's saved from an alternate universe in which he dies in a carriage accident, someone comments that there's a new guy working in the chip shop, and she could swear he looks elvish. In the Animated Adaptation, he looks and dresses like Elvis.
- A quick gag in The Shepherd's Crown, when the dying down of an elf's glamour and imperiousness is described as "the elvish was leaving the building".
- In The Dresden Files:
- In Death Masks, Harry Dresden goes on a tangent on how more than one Elvis could be worded as Elvises and then notes how that sounds like he was talking like Gollum trying to say "Elves". Gentleman Johnny Marcone is more than slightly bemused and confused after hearing this particular tangent.
- He also once accused Thomas of dressing too much like fat end-of-his-career Elvis. Thomas is a vampire, not an elf, but White Court vampires have a similar too-pretty-to-be-human allure.
- In the short story "The Return of the King" by Susan Wade and Don Webb, Elvis is an elven prince who originally came to Earth to try his hand at music. The fat, drug-addicted, dead Elvis from Real Life was merely a magical copy of the original Elvis, used as a Body Double to cover the real Elvis's return to his homeland.
- In Quantum Gravity, Zal, who is an elf does just about every genre of music, but is referred to as a rock star. And the incongruity earns him little love back home.
- In Esther Friesner's Elf Defense, one such elf is found to have once been a small-time rock star in the 1970s.
- In the Due South episode "Gift of the Wheelman", where the robbery suspects are dressed as Santas, the police accidentally round up Elvis impersonators for questioning instead of Christmas elves.

- In Discworld Noir, Lewton will say "Thank you very much" with an Elvis accent when a wizard informs him that glamours are "an elvish thing".
- In Warhammer Online: Age of Reckoning, the player can grow Elvish Parsley.
- In World of Warcraft, one April Fools joke introduced the Bard class - a new hero class which would attack enemies via Guitar Hero minigame. Had this actually been introduced, one could have expected to find lots of Night Elf or Blood Elf
rockstarsBards. As a Shout-Out to this trope, the Bards on the World of Warcraft announcement were Blood Elves.
- My Sims Kingdom. Forest Of The Elves. One is your classic wood elf, the other IS A ROCK STAR!!!

Woot: Uh, of course not.
Herman: [dressed as Elvis] That's not what you told me.
Woot: Herman, I distinctly said "ELVISH" impersonator.
- Rusty and Co.: "Level 8: #79" has a character making a not-so-subtle jab at Roxy, the elf bard:
The Viscount: Oh come now, my dear! Are you an Elvish performer, or merely an Elvish impersonator?
- Larry's silly song in VeggieTales's Lord of the Rings parody had him dressed as Elvis (and emulating his style) while singing a song about being in love with a girl who speaks Elvish. The reaction from the Legolas parody? "You're not a real elf! You're an Elvish Impersonator!"
- Melfis, the leader of the Elves in the videogame of Faxanadu was in two episodes of Captain N: The Game Master. He shared some facial features (not to mention the wardrobe) of the singer, but with blue skin. Well, his face was blue. Everything from the neck down was white.
- The ChalkZone Christmas Episode "When Santas Collide" depicted the head Christmas Elf as an Elvis Presley lookalike named General Elvis, who was voiced by Jess Harnell doing an impression of Presley.
