Rumex bucephalophorus, also known as horned, red, or ruby dock is an annual herbaceous plant that is part of the family Polygonaceae. The scientific name Rumex bucephalophorus was first described and published by Linnaeus in 1753 in Species Plantarum. Other scientific names have also been given to Rumex bucephalophorus such as Bucephalophora aculeata and Lapathum bucephalophorum.

Rumex bucephalophorus is native to the Mediterranean Basin and grows best in areas with little human intervention.
