"Acapella" is a song by American music duo Karmin. It was released on July 9, 2013 by Epic Records as the lead single from their debut studio album, Pulses (2014). The single was written by group members Amy Heidemann and Nick Noonan, as well as Sam Hollander and Boys Like Girls frontman, Martin Johnson, who produced the single.

The single was co-written by group members Amy Heidemann and Nick Noonan, along with Sam “S*A*M” Hollander, while production duties were handled by Boys Like Girls frontman Martin Johnson. The instrumental concept of the song was inspired by the film Pitch Perfect (2012), a movie about an all-A cappella singing group. The song itself is a mix of human voices with limited instrumentation. Over a "booming bass line," Amy raps about finding Mr. Right and realizing he wasn’t so perfect after all.

"Acapella" has received mixed reviews from music critics. Amy Sciarretto of the website PopCrush gave the song 4 stars out of 5, stating "Acapella is a song about gaining your independence from dudes who are duds. Thematically, it could be this decade’s answer to ‘Single Ladies,’ without being quite so anthemic and obvious." Adam Soybel at blog POP! Goes The Charts called it a "cute song", noting that "they sound like they’re having fun", but at the same time, pointed out the risks of releasing it as a single. Mikeal Wood of The Los Angeles Times gave the song a highly negative review, stating: "Released last month, 'Acapella' is bad, no doubt about it: lame melody, lame beat, lame rapping by Heidemann, who shamelessly copies herself copying Brown's staccato flow from 'Look at Me Now'".

"Acapella" entered the Australian ARIA Singles Chart at number seventeen for the week of July 28, 2013. The following week, it jumped to number eight, and has now jumped to number four, becoming the duo's second top-ten hit in Australia, following, and succeeding "Brokenhearted", which peaked at number nine. In New Zealand, the single is rising steadily, reaching a new peak of number nine, and is also following the success of "Brokenhearted", which peaked at number five. It was certified Platinum in New Zealand. Domestically, "Acapella" became their third single to chart on the US Billboard Hot 100, reaching number seventy-two. It Has Been Certified Platinum in Australia for Selling 140,000 Copies there.
