Sonic the Hedgehog is a video game for PlayStation 3 and Xbox 360 that was made to celebrate the fifteenth anniversary of the Sonic the Hedgehog franchise. It was developed by Sonic Team, published by Sega and directed by Shun Nakamura.

The game shares its name with two earlier video games, a manga, a television series, a comic book series and, of course, Sonic the Hedgehog himself. To disambiguate, the game has been called by a number of different aliases, including Sonic '06, Sonic 2k6, Sonic 2006, Sonic 360, Sonic PS3 (even though it was not exclusive to either console) and Sonic Next Gen. It was released on November 14, 2006.

This is the second Sonic game to receive an E10+ rating after Shadow the Hedgehog.
