- This article is about doors as they appear in Kirby & The Amazing Mirror. For doors in a more general context, see Door.
There is at least one Mirror Door in most rooms, excluding boss rooms, and Warp Star rooms. Some mirrors lead only one way through, after which Kirby cannot come back through the other way. Most others, however, lead both ways. Mirror Doors usually appear near the edge of a screen, though some appear in various places around a room. Some mirrors are hidden and can only be uncovered by destroying the blocks covering it. Yet others are only accessible with a special ability.
Mirror Doors appear in a variety of ways. In general, Mirror Doors appear as clear mirrors with a rotating star above and a border around them. Unvisited Mirror Doors have a blue halo around the star at the top. In the main room (Rainbow Route lobby), each Mirror Door, all of which lead to a separate area, has a special appearance reflecting upon the area behind the mirror. Each of the smaller lobbies also have such doors with special appearances, and two regular ones. The Dimension Mirror is accessible after collecting all eight Mirror Shards.
The Mirra enemy covers up a mirror and burrows in the ground when Kirby approaches too closely, leaving the mirror that was covered inaccessible until the player revisits the room again. To access the Mirror Door under a Mirra, Kirby must inhale and blow his breath at Mirra or use a ranged attack.

Two Mirror Doors make an appearance in subsequent installments in the Kirby series. The first is the Dimension Mirror, which appears again in Kirby: Triple Deluxe, at the end of DededeTour! The mirror is said to be responsible for Queen Sectonia's turn to evil, and it summons forth two enemies to do battle with King Dedede; in Shadow Dedede and Dark Meta Knight's Revenge. After defeating these foes, Dedede destroys the mirror.
The second door is known as the Black Mirror, which resembles the Dimension Mirror, but is black and thorned. It is responsible for the tribulations of Team Kirby Clash Deluxe's storyline, and is controlled by King D-Mind. Team Kirby is tasked with defeating this alternate-dimensional villain, and destroying the mirror with him inside.
