Matthew Harding (born September 27, 1976) is an American traveler, video game designer, and Internet celebrity who is known as Dancing Matt, for his viral videos that show him dancing in front of landmarks and street scenes in various international locations. Harding has since received widespread coverage of his travel exploits in major print and broadcast media outlets, and was hired by Visa to star in their Travel Happy campaign in 2008.

He is originally from Westport, Connecticut.

He began his game industry career working for a video game specialty store called Cutting Edge Entertainment. Harding later worked as an editor for GameWeek Magazine in Wilton, Connecticut, and then as a software developer for Activision in Santa Monica, California and then Brisbane, Queensland.

Harding claims that a sarcastic joke about the popularity of shoot 'em up games led Pandemic Studios to develop the game Destroy All Humans!, on which he received a conceptual credit. He said, "...didn't want to spend two years of my life writing a game about killing everyone...". He quit his job and began traveling, leading to the production of his first video, which was uploaded to YouTube in July 2006.
