The East Coast Classic, or ECC, was a regional yo-yo competition first held in late 2006 in Wilmington, Delaware. Organized by Tyler Severance, Matt Dougherty, and James Keenan. It was also held there in 2007 and 2008, at the Aldersgate Church near Mitchell's at the Concord Pike shopping center.
In 2011, the contest was hosted in Boston, MA, at Faneuil Hall. It was inagurated as the eastern component of the Triple Crown. To date, that was the last time that ECC took place.
