"Potential Breakup Song" is a song co-written and performed by American duo Aly & AJ, and is the first single from their second studio album, Insomniatic. It was a very successful single in the summer and early fall of 2007, topping many video countdowns, and becoming Aly & AJ's most successful single to date. At the time, was highest selling single by a Hollywood Records artist, as it was certified platinum by the RIAA for sales over 1,000,000 copies. Time magazine ranked "Potential Breakup Song" the ninth best song of 2007. The song received positive reviews from other music critics as well, many praising its lyrical content and its maturity, as well as the "adventurous" synth-based production.

There are two versions of this song played on the radio. One is the official album version, which is played on mainstream radio, while a version with all of the violence and sexual innuendo removed is played on Radio Disney. In the chorus, in "gettin' me", the edited version adds a "to" between "gettin'" and "me". In the middle-eight, in "without me you're gonna die", "die" is replaced with "cry."

A departure from their earlier guitar-based sound, "Potential Breakup Song" is primarily a three-minute-and-thirty-nine-second pop song. It makes heavy use of vocal processing effects during the verses, and its lyrical content is, as the title states, about a break-up, mentioning that "our album needs just one".

"Potential Breakup Song" debuted at number 77 on the US Billboard Hot 100 on July 5, 2007. The song peaked at number 17, becoming the group's best single performance on the Hot 100. As the song began to fall down the chart, dropping to number 50 about a month after its peak, the song recovered bounced back up to number 41 after Aly and AJ co-hosted MTV's TRL for one week. As of March 2009, the song has logged over 1,000,000 digital downloads in the United States, enabling it to be certified Platinum by the RIAA.
