Big Star Doors, or Star Doors, are a special sliding type of ★ door in Super Mario 64 and its remake, Super Mario 64 DS. Like other ★ doors, they restrict progress to certain parts of the Mushroom Castle until the player has the necessary number of Power Stars. Unlike normal ★ doors, however, Big Star Doors cover passages that are always required to open to complete the game. In the remake, only Mario can unlock a Big Star Door, but once it is unlocked, any character can enter it.

Four Big Star Doors exist in the games:

1. The first floor door leads to Bowser in the Dark World. Eight Power Stars (12 in the DS version) are required to open it.
2. The second door is in the basement and requires 30 Power Stars to be opened. Dire, Dire Docks and Bowser in the Fire Sea are behind it.
3. The third door is on the floor above the second floor lobby at the top of the stairs. 50 Power Stars are needed, and behind it are Tick Tock Clock, Rainbow Ride, and Wing Mario Over the Rainbow.
4. The last door leads to the final battle with Bowser. It does not require any Power Stars to open, but it has an endless staircase behind it unless Mario has at least 70 Power Stars (80 in the DS version). In the remake, if anyone other than Mario attempts to open the final door, that character will still encounter the endless stairs, regardless of the number of Power Stars.

In the Super Mario Mash-up in Minecraft, there is a painting of a Big Star Door.
