Abstract: A skateboard hubcap for protecting the wheel bearings of a skateboard from environmental contamination, such as dirt, sand, and water. The invention also enhances the general appearance of the skateboard by concealing the axle nut and bearings. The skateboard hubcap comprises a shield which covers the normally exposed wheel bearings, an axle receiving column which slides over the axle nut, and detents on the inner flat surfaces of the substantially cylindrical extension to secure the skateboard hubcap on place. A spacer is placed behind the axle nut to assure adequate clearance for the detents to lock onto the axle nut.
