Before and After Science is the fifth studio album by British musician Brian Eno.

Produced by Eno and Rhett Davies, it was originally released by Polydor Records in December 1977 in the UK and by US Island soon after.

Guest musicians from the United Kingdom and Germany helped with the album, including members of Roxy Music, Free, Fairport Convention, Can and Cluster.

Over one hundred tracks were written with only ten making the album's final cut. The musical styles of the album range from energetic and jagged to more languid and pastoral.
