In relation to motorsport governed by the FIA, Group N referred to a set of regulations providing 'standard' production vehicles for competition, often referred to as the "Showroom Class".

This contrasted with the Group A all-out competition production-derived vehicles. Group N cars are limited in terms of modifications made from standard specification. Group N was introduced by the FIA in 1982 to replace the outgoing Group 1 as "standard touring cars".
