Sonic the Hedgehog Spinball, also known as Sonic Spinball, is a 1993 pinball video game developed by Sega Technical Institute and published by Sega. It is a spinoff of the Sonic the Hedgehog series. Players control Sonic the Hedgehog, who must stop Doctor Robotnik from enslaving the population in a giant pinball-like mechanism. The game is set in a series of pinball machine-like environments with Sonic acting as the pinball.

Pinball games are a family of games in which a ball is propelled into a specially designed table where it bounces off various obstacles, scoring points either en route or when it comes to rest. Historically the board was studded with nails called 'pins' and had hollows or pockets which scored points if the ball came to rest in them. Today, pinball is most commonly an arcade game in which the ball is fired into a specially designed cabinet known as a pinball machine, hitting various lights, bumpers, ramps, and other targets depending on its design. The game's object is generally to score as many points as possible by hitting these targets and making various shots with flippers before the ball is lost. Most pinball machines use one ball per turn, and the game ends when the ball(s) from the last turn are lost. The biggest pinball machine manufacturers historically include Bally Manufacturing, Gottlieb, Williams Electronics and Stern Pinball.
