Missing on Lost Island (aka Ztracený ostrov (Czech), Verschollen Auf Lost Island (German)) is a 2000 Slovak adventure game developed by Mayhem Studios, and published by Bohemia Interactive.

The original intention of the title, according to Bonusweb.cz, was to make a serious adventure around the theme of pirates, unlike previous games like the comical The Secret of Monkey Island.

[5] Mr Bill's Adventure Land praised the impressive realistic movement in the game.
