"Numa Numa" is an Internet meme based on a video by American vlogger Gary Brolsma made after the song "Dragostea Din Tei" as performed by Moldovan pop group O-Zone. Brolsma's video, entitled "Numa Numa Dance", was released on December 6, 2004, on the website Newgrounds.com under the username "Gman250" and shows Brolsma lip-synching the hit song with lively gesticulations and dance moves. The video title is derived from the Romanian words "nu mă nu mă" that occur in the refrain of O-Zone's song. It was the first Numa Numa-themed video to gain widespread attention.

"Numa Numa Dance" has since spawned many parody videos, including those created for the "New Numa Contest", sponsored by Brolsma, which promised US $45,000 in prize money for submissions. His original video was named 41st in the 2006 broadcast of 100 Greatest Funny Moments by Channel 4 in the UK. The video was featured on Channel 4's Virtually Famous, and was ranked No. 1 in VH1's "40 Greatest Internet Superstars" in March 2007.

The Viral Factory estimated that by November 27, 2006, the video had been viewed over 700 million times.
