Vallendar is a municipality in the district Mayen-Koblenz, in Rhineland-Palatinate, Germany. It is situated on the right bank of the Rhine, approx. 4 km north-east of Koblenz. Vallendar is the seat of the Verbandsgemeinde („collective municipality“) Vallendar.

It is situated 5.7 km (3.5 mi) north of Koblenz and 12.3 km (7.6 mi) south of Neuwied. East of Vallendar rises the Westerwald, on the other side of the river the Eifel.
