Ravenser Odd, also spelled Ravensrodd, was a port in the East Riding of Yorkshire, England, during the medieval period, built on the sandbanks at the mouth of the Humber estuary. The name Ravenser comes from the Viking Hrafn's Eyr or "Raven's tongue" referring to the lost sandbank promontory, the modern successor of which is now known as Spurn Point. The town was founded by the Count of Aumale in the mid-thirteenth century, and had more than one hundred houses and a flourishing market by 1299, when it was granted a borough charter.
