Holbrook is an unincorporated community in west central Oneida County, Idaho, United States.
Holbrook was settled in the late 1890s by residents of Mendon, Utah and surrounding areas who were drawn to the area due to the availability of land to homestead. The town is named after Heber Angell Holbrook, an early Mormon Bishop in the town.
Holbrook lies at the intersection of State Highways 37 and 38, approximately 25 miles (40 km) west of Malad City, the county seat of Oneida County.
In 2013, a triple murder occurred in Holbrook.
