Danny Swain, better known by his mononymous stage name Danny! (/ˈdæniˈ/ dan-EE), is an American recording artist and record producer from Columbia, South Carolina.

Danny! is a former student of the Savannah College of Art & Design; he often wears an oxford shirt and pinstriped necktie, and has gained notoriety for prank-calling celebrities. In 2012 Danny! rose to prominence shortly following the proclamation by The Roots drummer Questlove that there was strong interest from Jay-Z; he was subsequently signed as the flagship artist to Questlove's re-launched Okayplayer Records after years of being loosely affiliated with the company. In support of the new venture Danny! made his television debut on Late Night With Jimmy Fallon in September 2012, premiering his song "Evil" alongside The Roots.
