This song was Super Junior's comeback single as a complete group since their subgroup activities in Mainland China and South Korea in 2008. It was Super Junior's most successful single in the music charts, winning a total of 10 recognitions during the song's promotional period.

"Sorry, Sorry" was written by Yoo Young-jin, who wrote "Don't Don," the title track of Super Junior's second album Don't Don. Yoo reportedly wanted create a song which is both equally fun and easy to listen. The song is a "polished and trendy" dance song, with influences of American funk and contemporary R&B, stimulated with a heavy electronic beat that is the genre of "urban minimal funky."

The music video was filmed from February 28, 2009, to March 1, 2009. A 30-second teaser of the video was released on Super Junior's official iple site on March 6, 2009, and the complete video was released on March 13, the same day as Super Junior's comeback performance on KBS's Music Bank. The video is SM Entertainment's first anamorphic formatted music video with an aspect ratio of 2.39:1. Throughout most of the video, only eleven members are seen dancing to most of the choreography, although the video does include all thirteen members of Super Junior. Heechul appears to be in the dance towards the end of the video, and Kibum only appears in solo shots.

The video starts off with an experimental scene, a woman's eye peeping through a key hole. She then pulls up her skirt, exposing her legs, and Super Junior member Kibum blindfolds himself; a small flame is burning an enclosed envelope, which is sealed with sealing wax. The woman then touches her lips and pulls off her pearl necklace. This scene is then engulfed to blackness and zooms to Super Junior, who are seen posing side-by-side in front of a white screen. Han Geng leads the group into a gentle sliding pose, and then they start dancing. In the song's dance bridge the members are tutting, with Eunhyuk in the lead. The whole music video is in black and white. The dance is choreographed by Nick Bass as well as Trent Dickens, who is known for working with international stars like Usher and Justin Timberlake. "Sorry,Sorry" Music Video currently has over 50 million views on YouTube, while the dance version has over 17 million views.
