Regional rail is a public rail transport service that operates between towns and cities. These trains operate with more stops than inter-city rail, and unlike commuter rail, operate beyond the limits of urban areas, connecting smaller cities and towns.

In North America (e.g. the United States), "regional rail" is often used as a synonym for "commuter rail", often using "commuter rail" to refer to systems that primarily or only offer service during rush hour while using "regional rail" to refer to systems that offer all-day service. In Europe, regional trains have their own category, often abbreviated to R (RB in Germany) or L (for local train).
