Olst is a town in the Dutch province of Overijssel, about 8 km (5 mi) north of Deventer.

In 1308, the dike along the river was built, and Olst became a stopover for the ships from Zwolle to Deventer.

[2] In the 15th century, the havezate (manor house) Averbergen was constructed on two yards from the former monastery Essen.

[2] The grist mill Bökkers Mölle was built in 1895, however the lower part dates from 1729.

The municipality was merged with that of Wijhe in 2001, keeping the name of the largest constituent part (Olst), until it was renamed Olst-Wijhe a year later.
