Arctostaphylos hookeri is a species of manzanita known by the common name Hooker's manzanita.
Arctostaphylos hookeri is a low shrub which is variable in appearance and has several subspecies. These are generally mat-forming plants or low bushes with small green leaves, dense inflorescences of white to pink flowers, and shiny egg-shaped or round red drupes.
- There are several subspecies including:

As of September 4, 2012, the U.S. Fish and Wildlife Service plans to designate Franciscan manzanita as an endangered species.
