Redbed refers to a type of sedimentary rock formation characterized by reddish or reddish-brown hues, caused by the presence of iron oxide minerals such as hematite and/or iron hydroxides. Redbeds are typically found in dry, arid regions where there has been little vegetation, weathering, or erosion. They can be composed of sandstone, shale, or siltstone, and often contain visible cross-bedding or other sedimentary structures indicating their formation by wind or water currents.

Redbeds are important in the oil and gas industry, as they are often associated with petroleum reservoirs. They can also be an important source of construction materials, such as building stone or decorative rock, due to their unique color and texture. Redbed formations can be found all over the world, but are particularly prominent in the southwestern United States, where they cover large areas in states such as Texas, New Mexico, and Arizona.
