IJhorst (Lower Saxony: De Rieverst) is a village in the municipality of Staphorst in the Dutch province of Overijssel. IJhorst is located in the Reestdal area on the border of Overijssel and Drenthe and has 1340 inhabitants (2007).

In IJhorst is a church built in 1823 with a loose bell chair. This church building was restored in 1995. The church is used by the Reformed Church of IJhorst / De Wijk. In addition, the village differs greatly from the rest of the municipality of Staphorst, because it is much less orthodox.

IJhorst has a number of campsites within its borders (including The White Mountains, the Vossen Castle, and The Braamsluiper), but there is barely middle class. However, on the first Saturday morning of each month, a well-known flea market will be held.
