Lindau is a village in southern Lower Saxony. It belongs to the municipality of Katlenburg-Lindau and is the only place in the district of Northeim in the Untereichsfeld region.

Lindau has a number of historically valuable buildings. The oldest building in the municipality of Katlenburg-Lindau today is the so-called Mushaus, whose roots go back to the 14th century. The tall Mushaus, visible from afar, has been on the coat of arms of the village of Lindau since 1951. With its walls several meters thick, it has survived the centuries and is considered one of the oldest fully preserved secular buildings in Lower Saxony. In addition to the Mushaus, the baroque Catholic church of St. Peter and Paul with its Louis Krell organ, the neo-Gothic brick Kreuzkirche church and the legendary Mordsmühle mill are also worth a visit.
