"In the Year 2525 (Exordium & Terminus)" is a 1969 hit song by the American pop-rock duo of Zager and Evans.

[17] Two lines of the song are sung by the inmate Murphy in the 1992 film Alien 3 immediately prior to his death.

Brief snippets are played in "The Time Is Now", the second-season finale of the TV show Millennium, which depicts an apocalyptic event.

In 2010, it was parodied as "In the Year 252525" in the seventh episode of Futurama's sixth season, "The Late Philip J. Fry", as Fry, Professor Farnsworth and Bender travel forwards through time to find a period in which the backwards time machine has been invented.

[19] The BBC Radio series 2525, a sketch show set in that year, featured a cover of the song with its first lyric as its introductory theme.

The first few verses of the song are used as the opening theme while the credits roll in the 2006 film Tunnel Rats.

Zager once said that a Time magazine cover from 1969 featured him and Evans with the caption "Even The Beatles would be jealous".
