Written by Pete Ham for their first Warner Bros. LP, Badfinger, it served as the opening track and sole U.S. single for said album.

2, AllMusic's Stephen Thomas Erlewine cited the track as a highlight from said album.

[1] Also from AllMusic, Matthew Greenwald said, "A bit of an odd choice to open Badfinger's Warner Bros. debut album, 'I Miss You' is, nevertheless, one of Pete Ham's finest-crafted ballads.

The overtly (and almost cloying) music and lyrical thrust is nicely balanced out by Ham's (and the group's) vocals.

"[2] Classic Rock History critic Janey Roberts also rated it as Badfinger's 8th best song.
