Katatonia is a Swedish metal band formed in 1991 by two friends in Stockholm. Since then, the band has moved through a variety of changes both musically and lyrically while maintaining their somber, depressive tone.

The principal men behind the band are vocalist Jonas Renkse and guitarist Anders "Blakkheim" Nyström. Usually Anders writes the bulk of the music and Jonas the lyrics.

They are good friends with [[{{Opeth}} Opeth]].

The debut album displayed the themes of sadness and loss through a lot of mystical and grim imagery alongside with anti-religious statements. The mystical edge and satanic imagery disappeared alongside the pentagram logo on Discouraged Ones to be replaced with more introspective lyrics. Depression, loss and other dark themes remained. With Viva Emptiness more abstract lyrics came around and are now seemingly a staple.

Anders says they are a "happy sad band".

!!This band provides examples of:
* AnimalMotifs: Birds show up in a lot of the albums' artwork.
* CallBack:
** "The Parting" has the lyrics "We have to walk along the wire". ''Viva Emptiness'' had a song called "Walking by a Wire".
** "The One You Are Looking For Is Not Here" also takes its title from a line in "Walking by a Wire".
* CarefulWithThatAxe
* CannotSpitItOut: In "Wait Outside".
* CoverVersion: They covered singer-songwriters Jeff Buckley and and Will Oldham.
* DespairEventHorizon: "Don't Tell a Soul", "Brave" and the list goes on...
* DownerEnding: Several songs, most notably the upbeat sounding "Omerta" [[spoiler: in which the narrator is arguably poisoned]]
* EpicRocking: "Velvet Thorns (Of Drynwhyl)" clocks 13:56 and "Tomb of Insomnia" 13:09
* ExactlyWhatItSaysOnTheTin: The ''Discouraged Ones'' track "Instrumental" is...well, an instrumental.
* HeyItsThatVoice: Opeth's Mike provides the harsh vocals on Brave Murder Day.
* {{Lighter And Softer}}/GenreShift: From ''Discouraged Ones'' onward, with their [[DeathMetal Death/]]DoomMetal approach shifting towards a {{Gothic Metal}}/AlternativeMetal one. ''Last Fair Deal Gone Down'' really cemented their current sound.
** The "Dethroned and Uncrowned" remixes of DEK are very much softer, though considering the mood not much lighter.
* MoodWhiplash: Subverted with "Omerta". While it sounds like a upbeat alternative rock song in contrast to the rest of the album it really isn't.
* MurderBallad: "Murder", obviously, and "We Must Bury You" and "Sweet Nurse". [[spoiler: An abstract song about corpses on windmills, a bullying-turned-murder event and a case of euthanasia respectively]]
* NoHoldsBarredBeatdown: "We Must Bury You". Doubles as a MurderBallad.
* PrecisionFStrike: Shows up a few times, most notably on the ''Dance of December Souls'' version of "Without God".
* ShoutOut: The album title Last Fair Deal Gone Down is a reference to a delta blues musician
* SuddenlyVoiced: The tenth anniversary remaster of ''Viva Emptiness'' adds vocals to the previously-instrumental "Inside the City of Glass". WordOfGod is that it was always intended as a vocal song, they just didn't have enough time left in the studio to record vocals for it.
* TakeThat: "Passing Bird" makes stabs at emo girls pretending to be depressed. Anyone seriously down would want to get better, not stay there to get attention.
** Given that ''Last Fair Deal Gone Down'' was released when emo-pop was still largely in its infancy, it was probably targeting mallgoths and nu-metal kids, both of whom were prone to much the same thing.
* TheEndOfTheWorldAsWeKnowIt: "Endtime" has the world end in fire.
* TitleDrop: "The Itch" contains the line "the great cold distance".
** In "Hypnone," one of the lyrics goes along the lines of "Tomorrow is so long/the Dead End King is here."
** "I Am Nothing" has the line "I have to get on with this/It's a decision for tonight."
* WildMassGuessing: The inlay of the jewelcase versions of Viva Emptiness and The Great Cold Distance sparked a lot of discussion among the fans for featuring a snippet from an IM conversation and a cockroach respectively.
* WordSaladLyrics: Especially on "The Great Cold Distance"
