Radnage is a village in Buckinghamshire, England. It is located in the Chiltern Hills, about two miles north east of Stokenchurch, six miles WNW of High Wycombe.

The village name is Anglo Saxon in origin, and means 'red oak'. It was recorded in manorial rolls of 1162 as Radenhech, which is when the village was given by the king to the Knights Templar.

The parish church of St Mary is of an unusual construction as its tower is in the middle of the church, as opposed to at one end. This design is common for churches associated with the templars. The wall paintings inside the church are of particular note, as they have been there since the Sixteenth century.

The man who reputedly killed the last bear in England is buried in Radnage, outside the church door. His gravestone is denoted by a man hunting a bear with a bow and arrow.
