"Tragedy" is a song released by the Bee Gees, written by Barry, Robin & Maurice Gibb, included on their 1979 album Spirits Having Flown. The single reached #1 in the UK in February 1979 and repeated the feat the following month on the US Billboard Hot 100.

Barry, Robin and Maurice Gibb wrote this song and "Too Much Heaven" in an afternoon off from making the Sgt. Pepper's Lonely Hearts Club Band movie in which they were starring. In the same evening they wrote "Shadow Dancing" which was performed by Andy Gibb (and reached #1 in the US).

Though not originally in Saturday Night Fever, it has subsequently been added to the musical score of the West End version of the movie-musical. The song knocked "I Will Survive" by Gloria Gaynor off the top spot in the US for two weeks before that song again returned to #1 for an additional week. In the US, it would become the fifth of six consecutive #1s, tying the record with the Beatles for most consecutive #1s in the US. This record was eventually surpassed in 1988 by American singer Whitney Houston when her single "Where Do Broken Hearts Go" became her seventh consecutive number-one hit on the Billboard Hot 100.

In 1979, NBC aired The Bee Gees Special which showed how the sound effect for the explosion was created. Barry cupped his hands over a microphone and made an exploding sound with his mouth. Several of these sounds were then mixed together creating one large boom heard on the record. The song is also playable on Rock Band 3.
