A small town drug store chain, Walden Drugs served pharmaceutical needs before the Great War.
- Concord - This two-story building is located on the same street as Wright's Inn and the Concord Speakeasy. There is a first aid box on the ground floor, behind the counter. An Expert wall safe can be found on the second floor on the southwest wall. Opposite the safe are a tool case and an ammo box.
- Forest Grove marsh - This building is on a corner towards the west side of town, but is inaccessible.
Walden Drug stores appear only in Fallout 4.
