"Hello Summer" is a song recorded by American country music singer Danielle Bradbery for her second studio album, I Don't Believe We've Met (2017).

A solo version by Bradbery was released digitally through Big Machine Records as the album's second promotional single on September 22, 2017.

"[1] In 2018, the song came full circle and was re-recorded as a duet between Rhett and Bradbery, with a few lyrical tweaks incorporating the updated title ("Goodbye Summer") and re-introducing the male perspective.

Sterling Whitaker of Taste of Country praised the song's pop-influenced production and wrote that "the give-and-take of Bradbery and Rhett's voices... gives the record added depth and appeal.
