2009 (unused)
This was made by Hayden 'Dock' Scott-Baron on 2009, but it was an unused logo.
2009–2011
The first logo was made out of the cobblestone as seen in the game.
2011–present
In 2011 Mojang released a new logo for Minecraft for its official release at Minecon. It looks similar to the previous logo, but a Creeper face can be seen in the "A." This logo actually first appeared on Beta 1.4.
