"Don't Cry" is a song by American hard rock band Guns N' Roses, two versions of which were released simultaneously on different albums. The version with the original lyrics is the fourth track on Use Your Illusion I (1991), while the version with the alternate lyrics is the 13th track on Use Your Illusion II (1991). Only the vocal tracks differ, and even then only in the verses; however, in those verses, not only are the words entirely different, but the meter and melody are also slightly different. There is also a third version, officially released only on the single for the song, which was recorded during Appetite for Destruction sessions in 1986.

Referred to as a power ballad, "Don't Cry" reached the top 10 in many countries, including peaking at number eight on the UK Singles Chart and number 10 on the US Billboard Hot 100. In Ireland, "Don't Cry" became Guns N' Roses' second number-one single, and in Finland, it became the second number-one hit from the Use Your Illusion albums. The song also topped Portugal's music chart, reached number two in New Zealand and Norway, and peaked within the top five in Australia, Denmark, and Switzerland. Andy Morahan and Mark Racco directed its accompanying music video.

Stradlin and Rose wrote the song (with the working title "Don't You Cry Tonight") in March 1985, shortly after Guns N' Roses was formed in Los Angeles. In fact, at a show in Atlantic City, New Jersey, on September 12, 2021, Rose claimed it was "the first song that was written for Guns N’ Roses.” In the 1993 video Don't Cry: Makin' F@*!ing Videos Part I Rose says that "Don't Cry" was their most Hanoi Rocks -influenced song. In the Special Collector's Edition of Rolling Stone dedicated to the band, Kory Grow quotes Rose:

It was [about] a girl that Izzy had gone out with, and I was really attracted to her, and they split up. I was sitting outside the Roxy, and I was really in love with this person and she was realizing this wasn't going to work – she wanted to do other things, and she was telling me goodbye and I sat down and just started crying, and she was telling me, 'Don't cry.' The next night, we got together and wrote the song in five minutes.

At the September 2021 Atlantic City show cited above, Rose told the crowd:

“I went over to Izzy’s and I threw some rocks at his window. He came to the window and was worried I came over there to kick his ass. We’d been in an argument for a few months. It was like the Blues Brothers. ‘We gotta get the band back together'...We sat down, and I was like, ‘Hey, I got some really depressing lyrics.’ He was like, ‘I got a really depressing guitar part.’ I was like, ‘Perfect, we got it made.'”

In his book Over the Top: The True Story of Guns N' Roses, Mark Putterford notes the song's contrast with much of the other material on the Illusion albums, citing Rose's "deeply ingrained whore/madonna dichotomy" and his "dew-eyed romantic cooing with tenderness." "Don't Cry" features Shannon Hoon of Blind Melon as a co-lead vocalist. Hoon sings an octave higher than Rose, and his voice is placed further back in the mix; Hoon also appears in the music video, singing alongside Rose during the helipad scenes. In his autobiography, Slash states that Hoon's harmony vocal "made that song all the more soulful." Along with "Estranged" and "November Rain," it forms a narrative inspired in part by the short story "Without You" by Del James.

The official music video for the song was directed by Andy Morahan and Mark Racco. John Linson was the producer of the video.
