Otterlo is a village in the municipality of Ede of province of Gelderland in the Netherlands, in or near the Nationaal Park De Hoge Veluwe.

The local resistance made use of a secret telephone connection from an electrician's house, which in 2021 still stands at the dorpsstraat, behind barber Prophitius, to communicate with the allies below the river Rhine (1944/1945).

During the war, multiple families hid Jewish people from the Germans.

One location was betrayed however, resulting in a raid in 1944 at the house 'De Lindenhof' at the Hoenderlooseweg.
