Black Hill is a mountain situated in Morro Bay, California, part of Morro Bay State Park.

It is one of a series of volcanic plugs called the Nine Sisters.

There is a forest of Monterey Pine (Pinus radiata) trees on Black Hill, called Fleming's Forest, planted by John Fleming, a park superintendent.

Nevertheless, he received it in full and used the surplus on Black Hill.

Many of the trees have died or are dying from pine pitch canker, a fungal disease which also threatens the Monterey pine's remnant native groves in Cambria and on the Monterey Peninsula.
