Mushroom Island Seeds

Mushroom fields within 1,000 blocks of spawn.

Mushroom fields are one of the rarest biomes, and the only one where hostile mobs do not spawn naturally on the surface. That makes them a safe place for a base, and mooshrooms give you endless stew.

Every seed below has mushroom fields within 1,000 blocks of spawn. They usually sit out in the ocean, so plan on a boat trip.

First things to do

Bring a boat and some food for the crossing; the biome is almost always surrounded by deep ocean.
Mycelium does not grow grass, so bring dirt if you want a farm on the island.
Spawners in dungeons and mineshafts under the island still work, so light them up or break them.

How these seeds were found

We ran our seed finder over random seeds with this exact quick pick, using the same world generator as the seed map, and kept the matches with the highest seed score. Every coordinate on this page comes from that check, for 26.3. Older or newer versions can place things differently, so check a seed on the map for your version. Last updated 2026-11-02.

Questions

Why are mushroom fields so far out?

The game puts them far out in the ocean, so they are rarely next to spawn.

Is the distance to the edge or the middle?

To the nearest mushroom fields sample, so you reach the shore of the biome at about that distance.
