Bad Bentheim is a town in the southwestern part of Lower Saxony, Germany, in the district of Grafschaft Bentheim on the borders of North Rhine-Westphalia and the Netherlands roughly 15 km south of Nordhorn and 20 km northeast of Enschede. It is a state-recognized thermal brine and sulphur spa town, hence the designation Bad (“Bath”). Also to be found in Bad Bentheim is the castle Burg Bentheim, the town's emblem.
