Niederheimbach (German: [ˌniːdɐˈhaɪmbax] ) is an Ortsgemeinde – a municipality belonging to a Verbandsgemeinde, a kind of collective municipality – in the Mainz-Bingen district in Rhineland-Palatinate, Germany.

The winegrowing centre belongs to the Verbandsgemeinde of Rhein-Nahe, whose seat is in Bingen am Rhein, although that town is not within its bounds. Since 2003, Niederheimbach has been part of the Rhine Gorge UNESCO World Heritage Site.

Niederheimbach lies between Koblenz and Bingen, right on the Rhine Gorge, only a short way northwest of the Rhine Knee. The place, which is found beneath or east of Bingen Forest (Binger Wald), has a built-up area stretching from 80 to 140 m above sea level. The highest mountain in the municipal area, at 618 m above sea level, is the heavily wooded Franzosenkopf (“Frenchman’s Head”), found south of the built-up area in Bingen Forest.

The council is made up of 13 council members, counting the part-time mayor, with seats apportioned thus:

	SPD	CDU	FWG	WNF	Total
2004	2	3	5	2	12 seats

Until its closure in the 1990s, the Märchenhain (“Fairytale Grove”) was a tourist attraction. A great number of the fairytale figures were nonetheless restored and have found a new place along an idyllic pathway near the community. There one can see many fairytales, such as Little Red Riding Hood, Hansel and Gretel and others along the Kuhweg (“Cow Way”).

• Right through the municipality runs Bundesstraße 9, linking Mainz with Koblenz.
• Bundesautobahn 61 can be reached roughly 13 km from the community at the Rheinböllen interchange.
• Niederheimbach railway station lies on the Mainz – Koblenz railway line.
