Old Red Sandstone is a type of sedimentary rock that is composed primarily of sand-sized particles of quartz, feldspar, and rock fragments. It has a reddish-brown colour and a rough, gritty texture.

It forms as a result of the accumulation of sediment in a terrestrial environment, such as a river delta or floodplain. It is named for its distinctive red color, which is caused by the oxidation of iron minerals within the rock.

Old Red Sandstone is an important geological formation in the United Kingdom, and is known for its rich fossil record of early land-dwelling organisms.
