"Last Name" is a song composed by country singer Carrie Underwood, Hillary Lindsey and Luke Laird. It is the third single from Underwood's second studio album, Carnival Ride. It was released in the United States on April 7, 2008, by which point the song had already charted. At the 51st Grammy Awards, the song won Underwood her third consecutive Grammy award for "Best Female Country Vocal Performance".
Allmusic picked the song as a "track pick", calling the song "Miranda Lambert filtered through Shania Twain", and dubbed it a "one night stand anthem." Rolling Stone picked the track as their favorite, saying "the most fun is "Last Name," where she gets wasted and runs off to Vegas with a guy she doesn't know." Blender awarded the song four out of five stars, describing the song as the "most irresponsible (and fun) moment on the new album involves one wild night, one too many shots of Cuervo and one unexpected ring." Billboard gave a positive review of the track, praising the lyrics: "It's a cleverly penned lyric that hilariously celebrates drunken debauchery" as well as summing it up as "a performance that combines soulful vocals, edgy intensity and sassy attitude into a delicious cocktail."
