A sled, skid, sledge, or sleigh is a land vehicle that slides across a surface, usually of ice or snow. It is built with either a smooth underside or a separate body supported by two or more smooth, relatively narrow, longitudinal runners similar in principle to skis. This reduces the amount of friction, which helps to carry heavy loads.

A toboggan is a simple sled traditionally used by children. It is also a traditional form of transport used by the Innu and Cree of northern Canada.
