Mushroom Islands are rare but in high demand since hostile mobs cannot spawn on Mycelium blocks and the Mooshrooms wandering the islands can be used as an unlimited food source.
We've searched far and wide to find the best Mushroom Island seeds in Minecraft. This list contains the biggest, prettiest, and most resource-heavy Mushroom Islands we could find! Each island is available for both Java and Bedrock players, with each version having its own structures both in and around the islands.
Best Minecraft 1.21 Mushroom Island Seeds
Bedrock and Java players can enjoy all of these islands, regardless of which version you're playing on. While the islands will hold their shape and size regardless of version, I've noticed that they will contain different structures depending on whether you are playing Bedrock or Java. However, that won't ruin the splendor of these islands. Coordinates have been provided for both versions so you can enjoy the mushroom life to the fullest.
Mushroom Island in Coral Reef
Seed: 3768965590915631201
Before heading to this Mushroom Island, gather plenty of wood, dirt, and seeds in the Forest you spawn in. You'll want to travel using a boat with a chest to ensure you can bring the most resources possible to the island. Since you'll be safe from most hostile mobs, you'll have plenty of time to farm and create a sustainable base. There are also plenty of Warm Ocean Ruins and shipwrecks to explore in the ocean if you find yourself running out of anything.

Three Connected Mushroom Islands
Seed: 1501813564714336673
A small strip of Mushroom Fields biome connects the three Mushroom islands in this world. They're located in a Frozen Ocean, so you'll be able to travel faster if you choose a path that is frozen over. Search carefully between the icebergs as there are a few Cold Ocean Ruins and shipwrecks around the island.

Massive Mushroom Island
Seed: -8936702305531883130
Located only around 500 blocks from Spawn, this is one of the largest Mushroom Islands on our list. The island is about 800 blocks long and just under 600 blocks wide. Due to its large size, you'll find plenty of Cold Ocean Ruins, shipwrecks, and even an Ocean Monument or two scattered around it.

Mushroom Seas
Seed: -1348008547075949990
This Lukewarm Ocean is home to four separate Mushroom Islands. The first and closest is the largest and the best place to build a base. The second is small and riddled with enough caves to serve as a personal mineshaft. Visiting island three reveals that it is covered in Mooshrooms, letting you easily gather plenty of Mushroom Stew. Lastly, the fourth island is the smallest and is best used as a small settlement to rest at while traveling to the nearby continent.

Long Island
Seed: 2842901415727422438
A long Mushroom Island is the star of this seed. The island is long and home to plenty of mushrooms and Mooshrooms. While exploring the Ocean around the island, you'll find five Ocean Monuments and lots of shipwrecks and Cold Ocean Ruins. If you look closely, you may find some underwater ruined portals as well.

Two Mushroom Islands make their home in the Warm Ocean of this seed. The left half of the larger island is in a regular Lukewarm Ocean while its right half is in the Warm Ocean with patches of Coral Reef.

Mushroom Ravine
Seed: 5374691412471917055
If you're into cave exploration, check out this Mushroom Island. In its center is a large ravine filled with untapped treasures just waiting to be excavated. When you're not deep into Deepslate, rest and gather resources on the safe surface of the island. Use the resources from the ravine to craft armor and tools for exploring the nearby shipwrecks and Ocean Monuments.

Arctic Mushroom Mass
Seed: -6769744659830011552
A giant Mushroom Island is as pleasing to the eyes as it is fun to explore. This one is found in the center of the Frozen Ocean next to Spawn. There is danger in the beauty as both Bedrock and Java players will find six Ocean Monuments in the seas around the island. If you're willing to take the risk, you could end up with the world of your dreams.

Warm Mushroom Cove
Seed: -1075708716890725434
My favorite Mushroom Islands are those surrounded by Coral Reefs. The brightly colored coral and the green-tinted waters add a really nice contrast to the Mushroom Islands that makes them pop. Visuals aside, the surrounding waters are filled with structures to explore. Explore shipwrecks, unearth Warm Ocean Ruins for sniffer eggs, and even try out a Trial Chamber beneath the larger Mushroom Island.

This mushroom island is small and sweet, making it the perfect place for a single-player survival base. The surrounding ocean contains Ocean Monuments for both Java and Bedrock players. As a bonus, Bedrock players will also find a Pillager Outpost and a Ruined Portal in the area near Spawn.
