"Pop a Top" is a country song written and originally recorded by Nat Stuckey in 1966. The first hit version was released by Jim Ed Brown in May 1967 as the third and final single from his album Just Jim. The song was a number 3 Billboard country single for Brown in late 1967. It was later revived by Alan Jackson as the lead-off single from his 1999 album Under the Influence. Jackson's version peaked at number 6 on the United States Billboard Hot Country Singles & Tracks chart, and number 2 on the Canadian RPM Country Tracks chart.

The narrator, a bar patron, asks the tender to open another bottle of beer for him, and then he'll go. He commences to tell the bartender about his grief because his girl left him, and either he'll hide it with beer, or he'll be at home remembering heɾ.
The sound of a metal "pop-top" can being opened was a novelty, and that is a significant factor in the creating of this song. The metallic click and hiss sound of opening this type of container is featured several times in the song.

The music video for Jackson's version was directed by Steven Goldmann, and features Cledus T. Judd. The video opens with Cledus opening a beer and suddenly finding himself at a black tie event, while Alan Jackson performs the song onstage. The video switches between shots of Alan and his band performing, Cledus socializing, and various people transforming into alternate (usually intoxicated or "country") versions of themselves whenever a glass passes in front of the camera. At the end, just as Cledus is about to kiss a beautiful woman, he finds himself back in his kitchen, alone, and frantically opens more beers to "get the magic back."

"Pop a Top" debuted at number 71 on the U.S. Billboard Hot Country Singles for the week of May 20, 1967.

"Pop a Top" debuted at number 49 on the U.S. Billboard Hot Country Singles & Tracks for the week of October 9, 1999.

"Pop a Top" is a popular drinking game in the American south. In this game, the song is played as a cue to tell players when to drink. When the lyric "pop a top, again" is sung, the player must then open and drink a beer before then next time the lyric repeats. When played to completion, the player will consume three beers during the course of the song.
