Described as an original game, Beat Sports is a collection of minigames based 'loosely' on sports like tennis, volleyball and golf.
"I'm thrilled to announce Beat Sports on this amazing, new platform," said Harmonix creative lead Jon Carter.
"Apple TV is the perfect home for this unique mixture of music, sports, and wacky fun."
The game is controlled using the new Apple TV's remote, which features a touch pad and allows for motion gestures.
"The new remote offers limitless possibilities for brand-new gameplay," Carter added.
