Under the [[Whyte notation]] for the classification of [[steam locomotive]]s, '''{{nowrap|0-8-0}}''' represents the [[wheel arrangement]] of no [[leading wheel]]s, eight powered and coupled [[driving wheel]]s on four axles and no [[trailing wheel]]s. Locomotives of this type are also referred to as '''eight coupled'''.
