Sonic the Hedgehog 2^[a] is a 1992 platform game developed by Aspect and published by Sega for the Master System and Game Gear. It is the sequel to the 8-bit Sonic the Hedgehog (1991) and follows Sonic as he attempts to get the Chaos Emeralds back to rescue his friend Miles "Tails" Prower from Dr. Robotnik. Like the first Sonic the Hedgehog, players run through levels at high speeds while collecting rings and defeating enemies. Although it shares the same title with Sonic the Hedgehog 2 for the Sega Genesis and their releases coincided, the games have little in common and share no levels.

Unlike the first 8-bit Sonic game, which was developed by Ancient, Sonic 2 was developed by Aspect, which did not interact with the Sega Technical Institute team developing the Genesis version. Sonic 2 was released in November 1992 to critical acclaim. Critics considered it an improvement over the first 8-bit Sonic and praised its visuals and gameplay. The game has been rereleased in numerous formats, including Sonic compilations and Nintendo's Virtual Console service.
