Sherwood Forest is the remnants of an ancient royal forest in Nottinghamshire, England, having a historic association with the legend of Robin Hood.

A royal forest, occasionally known as a kingswood, is an area of land with different definitions in England, Wales, Scotland and Ireland. The term forest in the ordinary modern understanding refers to an area of wooded land; however, the original medieval sense was closer to the modern idea of a "preserve" – i.e. land legally set aside for specific purposes such as royal hunting – with less emphasis on its composition. There are also differing and contextual interpretations in Continental Europe derived from the Carolingian and Merovingian legal systems.
