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

In 1277, Helferskirchen had its first documentary mention under the name Langesain in connection with Niedersayn, Karnhöfen, Kuhnhöfen and Blaumhöfen.

The community's arms take the shape of a late Gothic rounded shield with a horizontal upper edge and sides meeting it at right angles.

In red, the Trier cross can be seen, and in black is a stylized representation of the church after its expansion in 1769, which is how it still looks today.

The nearest InterCityExpress stop is the railway station at Montabaur on the Cologne-Frankfurt high-speed rail line.
