"Day by Day" is a folk rock ballad from the 1971 Stephen Schwartz and John-Michael Tebelak musical Godspell.

It is the third song in the show's score and is reprised as the closing number for the 1973 film version.

[2] The song's refrain follows a prayer ascribed to the 13th-century English bishop Saint Richard of Chichester: The version in Godspell follows more closely the wording in Hymn 429 of the 1940 Hymnal: "Day by Day" was first a hit in Australia, where both Judy Stone and Colleen Hewett released competing versions of the track in late 1971.

In 1972, a version of the song from the album Godspell (1971) by the original off-Broadway cast was released as a single in the US, and attributed simply to the group name "Godspell".

Robin Lamont was the lead singer, uncredited.
