Bofedales (singular bofedal), known in some parts of Peru as oconales, are a type of wetland found in the Andes. They are a feature in the land use and ecology of high Andean ecosystems. They form in flat areas around ponds or streams and may be permanent or seasonal, and they can be man made or natural. Bofedales are associated with organic material in the soil and their green colour often contrasts with that of the drier surrounding landscape.

They are found at elevations exceeding 3,800 metres (12,500 ft) above sea level. Bofedales absorb the limited amount of water derived from snow, glacier meltwater and rain showers, storing it in ground and slowly releasing it. Their vegetation is dominated by cushion plants. Numerous animals including birds, mammals and invertebrates occur in bofedales. They are used by humans, who have created new such wetlands through irrigation, but human activities can also be a threat to these ecosystems.
