Austin Griffiths Manzanita (Arctostaphylos 'Austin Griffiths') is a large evergreen shrub in the Heath family (Ericaceae). It is a hybrid between A. densiflora 'Sentinel' and A. manzanita 'Dr. Hurd'. It was introduced in the 1980's by Native Sons Nursery in memory of conservationist and naturalist Austin P. Griffiths.

The bark is maroon to dark red, with dark red stems, glossy sage-green foliage, and large clusters of of pale soft pink flowers. One of the earliest blooming manzanitas in early winter, it provides a valuable nectar source for hummingbirds, bees, and other pollinators. The berries are consumed by many mammals, and are also a food source for Indigenous Peoples.

The natural habitats for manzanitas are chaparral and openings in oak woodlands, which provide dry, sunny locations with excellent drainage.

This manzanita is striking as a specimen or informal hedge. Although it is a large shrub, it can be shaped and grown as a small tree. It prefers a sandy loam soil but does well in clay as long as it doesn't stand in water. More garden tolerant than 'Dr. Hurd', 'Austin Griffiths' accepts occasional irrigation but is exceptionally drought tolerant once established.
