"Bohemian Rhapsody" by Queen is a really catchy song, isn't it? Pretty much everyone can recognize the distinctive and complex melody, most people know the lyrics (at least approximately), it's a melding of numerous musical genres from rock to opera (thus lending itself nicely to being played with using other genres as well), and it also has a rather famous and recognisable music video. Thanks to its distinctive nature and Small Reference Pools, it's become quite a common subject for Parody.
There are several common approaches. The first is to keep the melody more or less intact but change the lyrics to suit a new, comic purpose. The second is to keep the song more or less the same, but have it sung by unlikely or inappropriate stand-ins for Queen (such as the crew of the U.S.S Enterprise) or in much sillier or inappropriate voices, and a third is to keep the lyrics the same but change the melody from a dramatic fusion of rock and opera to something a bit less... bombastic. Then, once you're done, all you need to do is replace the 'Bohemian' part of the title with something more appropriate to your current purposes so that the title becomes "[X] Rhapsody", and bingo!
Since any of these options allow for endless fun to be had with the song, it's a popular target for fandom parodies. Of the different sections of the song to parody, popular ones include the 'ballad' section ("Mama, just killed a man...") and especially the 'opera' section ("I see a little silhouetto of a man" to "Beelzebub has a devil put aside for me for me, for me!").
While the song is subject to numerous parodies, the music video for the song is itself quite well-recognised and thus also subject to frequent parodies and visual homage. The stock visual parody in this case is the instantly recognisable image of four people arranged in a 'diamond' formation against a dark background, with the lighting arranged to suggest that their heads are disembodied (an image frequently used through the video, taken from the cover of the band's second album).
- Briefly in Frozen II. At one point during "Lost in the Woods", there's a shot of Kristoff's head being flanked by three reindeer heads, lighted to resemble the opening shot of the video.
- Done with the British Royal Family in the Spitting Image sketch song "We Are The Royal Family", which is musically a parody of "We Are the Champions", but shows the Royals' heads with the same positions and lighting as Queen's at the start of their music video.
- An episode of Father Ted features the hyperactively annoying Father Noel Furlong subjecting everyone he's stuck in a cave with to an impromptu solo rendition of the song in which he does all the parts himself.

- Ninja Sex Party's "I Don't Know What We're Talking About": At one point in the song, Ninja Brian starts repeatedly playing the same note as Danny sings the next verse in a different style to the rest of the song.

- At a show in Canberra, Australia, Ross Noble was delighted to discover that an audience member in the front row worked for the Australian Bureau of Statistics: the government agency that, amongst other duties, conducts the 5 yearly national census. Ross then ad libbed a lengthy bit where he was a census taker asking an imaginary person a series of questions, and then repeating their answers back; the answers gradually building up into the lyrics of "Bohemian Rhapsody".
- Double Dragon Neon parodies the ballad section during the bridge of Skullmageddon's defeat song, "Dared To Dream".

- In "Art's Dream", the developer-created Story mode within Dreams, the nightclub bouncer's song asking you for the password has him hit the pose from the music video and album cover during the chorus.
- Neversoft spared no time doing the Bohemian Rhapsody performance in Guitar Hero: Warriors of Rock, complete with over-the-top gestures in the operatic section. When the motion capture data from that song got backported to World Tour by the World Tour Definitive Edition team, it did not take long for people to come up with some rather interesting band lineups.

- Youtube user and renowned Formula One-based Song parodyist Sim Dane actually did a twofer:
- First is "Bohemian Robsody", with former Polish F1 driver Robert Kubica as the central character;
- Second is "Bonomian Rhapsody", focusing this time on 7-time and reigning World Drivers' Champion Lewis Hamilton and his recurring tire troubles (the name is derived from Lewis' Senior Race Engineer Peter "Bono" Bonnington.)
- Bohemian Catsody
- The My Little Pony: Friendship Is Magic episode "The Show Stoppers", which revolves around the Cutie Mark Crusaders entering a Talent Contest, features a brief recreation of the video's opening shot at the start of the episode's main song (which otherwise bears little resemblance to "Bohemian Rhapsody" itself) with the CMC taking the band's place.
- A rather hilarious video created by a young guy from Indonesia made a parody of the titular song, which went viral in 2020. But the real hilarity comes from the lyrics themselves. It turns out he wasn't singing about his lover, instead, he was singing about some kind of random food menu he wants to order such as iced tea and French fries. For some good reasons, everything that he sang is all about food. Talk about Word Salad Lyrics with a fusion of Overcomplicated Menu Order.
