A milestone is one of a series of numbered markers placed along a road or boundary at intervals of one mile or occasionally, parts of a mile. They are typically located at the side of the road or in a median. They are alternatively known as mile markers, mileposts or mile posts (sometimes abbreviated MPs). Mileage is the distance along the road from a fixed commencement point.

Milestones are constructed to provide reference points along the road. This can be used to reassure travellers that the proper path is being followed, and to indicate either distance travelled or the remaining distance to a destination. Before GPS such references were also used to by maintenance engineers and emergency services to locate thier position on maps etc.
