Heiligenroth is an Ortsgemeinde – a community belonging to a Verbandsgemeinde – in the Westerwaldkreis in Rhineland-Palatinate, Germany.

The community's industrial park is separated from the main centre by this Autobahn, lying to its north.

While the Cologne-Frankfurt high-speed rail line was being built, the community was also shielded by a noise barrier.

The so-called industrial park (Industriegebiet) busies itself mainly in supplying the area with various service and shopping facilities such as supermarkets, a building centre, a furniture warehouse and filling stationss.

Among public institutions there are one kindergarten, a fire brigade, playgrounds, a sporting ground with clubhouse and a beach volleyball court, a parochial centre, the Vogelsanghalle (“Birdsong Hall”) with a bowling alley for major events, the community administration with a youth centre, four tennis courts and a clubhouse, and a Catholic parish church.
