The swamp or swampland is a wetland biome where slimes, frogs, and bogged can spawn, and it is the only biome where swamp huts can generate. It is vegetated by unique swamp oaks covered in vines, firefly bushes, lily pads, and more.

Generation

Swamp biomes typically generate in relatively flat terrain near sea level, in regions with very high erosion and cool to moderate temperatures. River biomes cannot flow through swamps, but may merge with swamp waters where a river ends at the swamp boundary.

They commonly border plains, taigas, forests, birch forests, and dark forests, sometimes entirely enclosed by swamps. Windswept hills and their variants commonly generate next to swamps, often forming mountain ranges around them.

Swamps do not directly border oceans, though their bodies of water may connect when a river or submerged beach biome separates the swamp from ocean. In warmer climates, swamps transition into mangrove swamps.

Dripstone caves sometimes generate beneath swamps, while lush caves may generate instead if humidity is high. Sulfur caves might generate if weirdness is low. Ice caves rarely generate, doing so near cooler regions closer to the coast.^{[upcoming: Fourth Drop 2026]}

Description

Swamps have sparse oak trees which can grow on land or in shallow water and generate with vines growing on them. Mushrooms are more common here than in most Overworld biomes, mostly generating in dark areas or under trees. In Bedrock Edition, huge mushrooms can generate as well. Sugar cane is found more commonly growing on shores, and seagrass litters the bottom of flooded areas. Firefly bushes and blue orchids grow among the grass, the latter of which are found exclusively in swamps. Lily pads are scattered across the surface of the water and dead bushes dot the surface of the land.

Swamp biomes, alongside mangrove swamps and deserts, can generate underground fossils. A swamp rarely generates swamp huts, housing a witch and a black cat. Only witches can spawn in and around the hut. Villages sometimes generate next to a swamp, where they spawn unique swamp villagers. ‌^{[Bedrock Edition only]} Otherwise, the only way for these villagers to spawn is either by being bred in a swamp, or curing a zombie villager that spawned in a swamp.

Abandoned camps sometimes generate in swamps.

Swamps have elevations low enough to go below sea level throughout much of the area. A large portion of swamps is flooded, where patches of clay are found on the lakebed, although deeper water only has a gravel floor. The shores of swamps may have marsh-like terrain, where the shores are very irregular, often without smooth transition, and with some small puddles generated. Sand or gravel disks do not generate.

Water in swamps takes on a gray-green color. Underwater fog is thick here so that visibility is lower than in other biomes underwater. Additionally, unlike other Overworld biomes, swamps have varying tints for grass blocks, short grass, leaves, and other plants, following a noise algorithm.

With Vibrant Visuals, swamps have a unique brown-green sky color, and stronger volumetric fog effects, fading the sun and sunlight.

Mobs

Slimes may spawn in swamps during the night, exclusively between Y=50 and Y=70, making swamps and mangrove swamps the only places where slimes can be found above ground. Their spawn rate is affected by the moon phase, spawning most often during full moon and not spawning at all during new moon. Bogged add an additional threat to the night, thunderstorms, or caves,‌^{[JE only]} as their poison arrows can increase the danger of hostile mobs.

The following mobs naturally spawn here:

History

Java Edition

Java Edition Alpha
v1.2.0	preview	Added biomes, including swampland. However, the biome itself was completely different from its modern counterpart.
v1.2.0	preview	Swamplands are defined by having a rainfall value of 40% or greater and a temperature value between 50% and 70%.^[verify]
Java Edition Beta
1.8	September 3, 2011	Notch teased a screenshot of the new swampland biome, with oak trees with vines.
	Pre-release	The old swampland biome was removed as part of the biome overhaul and replaced with the new swampland. Old swampland biomes from the original biome generation are not converted into the new swampland except by coincidence.
		Swampland oak trees, vines, marsh-like areas and dead bushes now generate. Foliage and grass is now a lush green color, akin to forests.
		Snow no longer generates in swamplands.
Java Edition
1.0.0	Beta 1.9 Prerelease	Grass, leaves and water blocks are now tinted a grayish green on swamplands. However, this change resulted in biome color and biome transitions becoming essentially nonexistent.
		Water in swamplands receives a unique tint ( #E0FF70) that is applied to its base blue color.
		Lily pads now generate in swamplands.
1.1	12w01a	Color transitions in swamplands have been fixed and smoothed.
1.1	12w01a	Changed the color of the water tint to #E0FFAE.
1.4.2	12w40a	Added witch huts, which may generate in swamplands.
1.4.2	12w40a	Slimes now spawn in swamplands.
1.7.2	13w36a	Swampland is now required for the new "Adventuring Time" achievement.
1.7.2	13w38b	Marsh-like areas and dead bushes no longer generate in swamplands.
1.8	14w26a	Marsh-like areas and dead bushes generate in swamplands again.
1.10	16w20a	Added fossils, which can generate in swamplands.
1.13	18w14a	Seagrass now generates in swamplands.
	18w15a	#617B64 changed the color of swamp water.
	18w19a	"Swampland" has been renamed to "Swamp".
	pre5	The ID `swampland` has been changed to `swamp`.
1.14	18w43a	Drowned no longer spawn in swamps.
September 28, 2019		During MINECON Live 2019, the swamp came in second place in the Biome Vote; mangrove trees, boats with chests, and frogs would be added.
1.18	Experimental Snapshot 1	Swamp biomes currently do not generate correctly.
	experimental snapshot 2	Swamp biome generation has been fixed.
	experimental snapshot 3	Swamps are less likely to overlap cold or dry biomes.
	experimental snapshot 3	Hanging water is no longer placed in swamps.
	experimental snapshot 4	Swamps are less likely to extend far out from the coastline.
	experimental snapshot 5	Swamps have been moved slightly more inland.
	experimental snapshot 5	Swamp oak trees are now able to generate in slightly deeper water than before.
	experimental snapshot 6	Swamps are now able to generate in dry areas, making them less fragmented overall.
	21w37a	Prior to the removal of numerical biome IDs, this biome's numerical ID was 6.
October 16, 2021		The Wild Update was announced at Minecraft Live 2021, showing in-game clips of previously-announced Biome Vote content, along with new features such as mud, fireflies, tadpoles, and frogs.
1.19	22w11a	Added frogs, which spawn in swamps.
1.19	22w14a	Swamps in warm areas have now been replaced by mangrove swamps.
1.20	23w17a	"A Familiar Room" may now be played in swamps.
1.20.5 Experiment Update 1.21	24w07a	Bogged now spawn in swamps.
1.21.5	25w05a	Added firefly bushes, which can generate in swamps.
26.3	snap1	Added abandoned camps, which can generate in swamps.
