Mangrove Swamps are essentially an alternative version of regular Swamp biomes in Minecraft, with deeper waters, frogs, fish, and mangrove trees' uniquely red wood.
They were introduced in The Wild Update in Minecraft 1.19, along with Ancient Cities. If you're looking to experience them in their full glory, this list contains some of the best, most unique, biggest, and most resource-filled Mangrove Swamps there are in Minecraft 1.20.

While the structures may vary between the two versions, these seeds will function perfectly whether you play on Minecraft Bedrock Edition or Java Edition.
Biome Sprinkles
Seed: -9134349127256840036
This huge Mangrove Swamp has other biomes sprinkled throughout it. You can find Desert, Jungle, Forest, Savannah, and Plains biomes in little pockets. It lets me live a fulfilling Mangrove Swamp life with easy access to the flora and fauna of the other areas. You could also play with friends, and each player could take one of the pockets to build their base on. You could also keep the beautiful swamp to yourself and turn the pockets into farms, animal exhibits, or anything else you can think of.

Witches' Swamp
Seed: 6159010377207402766
This seed starts you off on the edge of a Mangrove Swamp between a Plains and a Savanna biome. The Mangrove Swamp appears extremely large, but it is actually one-half of a giant Swamp biome, with a regular Swamp making up the other half. Sprinkled around the two are pockets of other biomes, like Savannahs and Flower Forests. Be careful when traversing the regular portion of the Swamp, as a few Witches have made it their home.
