Dragon's Lair: The Legend is a 1991 side-scrolling platform video game for the Nintendo Game Boy developed by Elite Systems. The game is part of the Dragon's Lair franchise and stars Dirk the Daring, who explores the world attempting to collect all 194 fragments of the mythical Life Stone. The gameplay is an extreme departure from other games in the series as it includes no enemies and aside from its protagonist, no other established characters. It does however retain the grueling difficulty that the series is known for.

The player can use either the A or B button to jump and left or right on the control pad to walk. The Start button pauses and the Select button resets if pressed on the pause screen.

The goal of the game is to move screen-by-screen collecting all 194 fragments of the Life Stone, then reach the final screen where the Good Knight lies in a deathlike trance. Each screen has a set width and the player advances to the next by reaching the edge. Dirk begins with 10 lives and loses a life by either landing on a deadly object (certain spikes, rail tracks, deadly water), falling from a great height, or depleting all of his energy meter. Dirk has no weapon, as there are no enemies or bosses. There is also no on-screen display that shows the player their remaining lives, energy meter, number of Life Stone fragments collected, or score. Only after a death does the game show the remaining lives and fragments collected. The score is revealed after a game over.

The world consists of 11 distinct regions covering themes from the medieval Dragon's Lair setting.
