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 1.21.

Flooded Mangroves
Seed: 687764971783484490
Oftentimes, the floors of Mangrove Swamps are covered in mud. Because this Mangrove Swamp is next to the ocean, its floor is smothered in water rather than mud. This means you'll need to worry more about attacks from Drowned than other dangerous mobs. On the bright side, it also means that you'll be able to survive off fishing and growing crops very easily.

Giant Mangrove Life
Seed: 4586360654228038863
You may not spawn in this Mangrove Swamp, but it sure is hard to miss. The swamp covers over 1,500 blocks and is filled with small pockets of other biomes, like the Desert and River pictured above. Each of these pockets gives you new materials and space to create new builds hidden from the rest of the world. There are a total of six Trial Chambers in and around the main portion of the swamp, each of which can be found by getting Trial Explorer Maps.
