Alex Kidd: The Lost Stars is an arcade platform game developed by Sega for the Sega System 16, and later ported to the Sega Master System. The Master System version was made available on the Wii Virtual Console in 2009.

The player assumes the role of Alex, and in the arcade version, the second player controls Stella in co-op mode. The game consists of six levels, each with a miracle ball to collect at the end of it. Once complete, the levels are repeated in a second "loop".
