'''Oxisols''' are a [[soil]] order in [[USDA soil taxonomy]], best known for their occurrence in [[tropical]] [[rain forest]] within 25 degrees north and south of the [[Equator]]. In the [[World Reference Base for Soil Resources]] (WRB),<ref>{{Cite web|url = https://wrb.isric.org/files/WRB_fourth_edition_2022-12-18.pdf|title = World Reference Base for Soil Resources, fourth edition|author=IUSS Working Group WRB|year = 2022|publisher = International Union of Soil Sciences, Vienna}}</ref> they belong mainly to the [[ferralsol]]s, but some are [[plinthosol]]s or [[nitisol]]s. Some oxisols have been previously classified as [[laterite]] soils.
