Leucothoe davisiae is a species of flowering plant in the family Ericaceae known by the common name Sierra laurel.

It is native to California in the Sierra Nevada and the Klamath Mountains, in which its distribution extends just into southwestern Oregon.

Leucothoe davisiae is a shrub growing in wet mountain habitat, such as bogs.

The inflorescence is a hanging cluster of many small urn-shaped white flowers, not unlike those of manzanitas.

The fruit is a capsule about half a centimeter long containing many tiny winged seeds.
