If You See Her, Say Hello

"If You See Her, Say Hello" is a song by American singer-songwriter Bob Dylan from his 15th studio album, Blood on the Tracks (1975). The song is one of five on the album that Dylan initially recorded in New York City in September 1974 and then re-recorded in Minneapolis. The later recording, made on December 30, 1974, was produced by Dylan's brother David Zimmerman, who was not credited. The recording later became the album track and the B-side of the "Tangled Up in Blue" single, released in February 1975.

The complete New York recording sessions of "If You See Her, Say Hello" were released on the deluxe edition of The Bootleg Series Vol. 14: More Blood, More Tracks in 2018, with the first take of the song, recorded on September 16, 1974, also included on the single-CD and 2-LP versions of the compilation. The second take of the song, from the same September 16 session, had been released in 1991 on The Bootleg Series Volumes 1–3 (Rare & Unreleased) 1961–1991. The deluxe version of The Bootleg Series Vol. 14 also included a remix of the December 1974 master issued on Blood on the Tracks. The song received generally positive reviews from music critics, being named by some as an album highlight, and it has been included on several lists of Dylan's best songs. Dylan's first live performance of the song was on April 18, 1976, at Civic Centre, Lakeland, Florida, and featured new lyrics. An Italian version of the song was recorded by Francesco De Gregori, titled "Non Dirle Che Non È Così".
