Glandorf is a municipality in the district of Osnabrück, in Lower Saxony, Germany.

The name Glandorf derives from Glanathorpe - which means settlement on the creek Glane - and was first mentioned in records in 1070.

The municipality includes Glandorf and six local subdivisions which are Averfehrden (formerly Narendorf), Schierloh, Schwege, Sudendorf, Westendorf, and Laudiek.

The oldest parts of the Roman Catholic Church St. Johannis (St. John the Baptist) date from the 13th century and were documentary mentioned the first time in 1275.

In 1636 the church was burned down by Swedish troops during the Thirty Years' War and was rebuilt with the old material.
