"Always Look on the Bright Side of Life" is a comedy song written by Monty Python member Eric Idle that was first featured in the film Monty Python's Life of Brian and has gone on to become a common singalong at public events such as football matches as well as funerals.

The song touches on the British trait of stoicism with the "stiff upper lip" spirit in the face of adversity, and became immensely popular. It reached number three on the UK Singles Charts, and the 2012 Summer Olympics closing ceremony in London featured a live performance of the song by Idle.

Whilst trying to come up with a way of ending the film Monty Python's Life of Brian, Eric Idle wrote an original version of the song which was sung in a more straight fashion, which the other Python members eventually agreed would be good enough for the end of the film. However, Michael Palin noted in his diary for 16 June 1978 that during a script meeting, "Eric's two songs — 'Otto' and the 'Look on the Bright Side' crucifixion song — are rather coolly received before lunch." Despite being initially underwhelmed, the group warmed to Idle's efforts and the song was retained. While practicing during a break in filming, Idle found that it worked better if sung in a more cheeky manner. This new version was used in the film and became one of Monty Python's most famous compositions.

At the relevant point in the film, Brian Cohen (played by Graham Chapman) has been sentenced to death by crucifixion for his part in a kidnap plot. After a succession of apparent rescue opportunities all come to nothing, a character on a nearby cross (played by Eric Idle) attempts to cheer him up by singing "Always Look on the Bright Side of Life". As the song progresses, many of the other crucifixion victims (140 in all, according to the script, though twenty-three crosses are actually seen on screen) begin to dance in a very restricted way and join in with the song's whistled hook. The song continues as the scene changes to a long-shot of the crosses and the credits begin to roll. An instrumental version plays over the second half of the credits.
