The third season of America's Best Dance Crew premiered on January 15, 2009. The season was once again hosted by Mario Lopez and featured Layla Kayleigh as the backstage correspondent. Lil Mama, JC Chasez, and Shane Sparks returned as the judging panel. This was the first season without a special casting episode. In the live finale, which aired on March 5, 2009, Quest Crew was declared the winner.
Similar to the first season, nine dance crews were selected to compete on America's Best Dance Crew, as opposed to ten. While the crews were not officially divided into the usual four regions (East Coast, West Coast, Midwest, and South) as with the previous two seasons, the regions were still listed on each crew's banner. This was also the first season to showcase a crew from the Caribbean. Team Millennia, who was eliminated during the Season 2 casting special, returned as one of the nine official dance crews.
The crews performed to the songs of their choosing. Then, the judges chose the bottom three crews to compete in a sudden death dance battle to "Live Your Life" by T.I. Rynan "Kid Rainen" Paguio from JabbaWockeeZ temporarily guest judged in place of JC Chasez, who later returned the following episode.
Each crew was given a physical activity/exercise to incorporate into their routine.
The crews took inspiration from Britney Spears' music videos to create their routines. Andre Fuentes, Spears' choreographer, assigned additional challenges for the crews to complete.
The crews performed to cliché songs that spurred uncool and silly dance crazes. Each crew had to incorporate their respective song's dance into their routines, while also trying to make the moves look fresh.
The crews had to perform their routines utilizing various magic tricks and illusions.
The episode started off with a group performance, choreographed by Napoleon and Tabitha D'umo, featuring Ludacris' "What Them Girls Like" and Beyoncé's "Single Ladies".
The two remaining male crews then battled against the two remaining female crews. Each crew had to emulate a male or female superstar's music video, and were challenged to incorporate the spirit of the video into their choreography.
The crews competed against each other in two challenges: the Hip-Hop Decathlon and the Last Chance Challenge. After the mid-show elimination, the top two crews performed their routines for the Last Chance Challenge.
The three remaining crews had to demonstrate their versatility by creating a routine that incorporated five different hip hop dance styles. The competitors were given the same five styles and songs, and received help from five guest ABDC alumni from the previous two seasons. Each alumnus/alumna was assigned to one of the dance styles the crews were responsible for.
The two finalists were given one last chance to perform before the lines opened for the final voting session of the season.
The eliminated crews returned and performed with the finalists for a collaboration. The judges each picked three crews that complemented each other and their dance styles. Instead of going head-to-head, Quest Crew and Beat Freaks teamed up for their last performance.
