West Side Island (ウエストサイドアイランド Uesuto Saidoa Irando?) is the main setting of Sonic the Hedgehog 2. It is an island that Sonic the Hedgehog visited after saving South Island from Dr. Robotnik and where he first met Miles "Tails" Prower. Many zones of the island make reappearances in later games, even if West Side Island itself is not mentioned.
