Lauenförde is a municipality in the district of Holzminden, in Lower Saxony, Germany.

The arms were granted in 1927 and based on a seal of the Amt Lauenförde from 1779.

The lion is the so-called Welfen-lion, indicating that the town belonged to this family.

Lauenförde is situated on the Weser and used to be one of the major crossing points of this river.

It has also been stated that the arms are canting, derived from Löwenfurt (Lion-ford).
