Black Mountain State Forest is a 795-acre (322 ha) state forest in Haverhill, New Hampshire, on the western slopes of Black Mountain, a 2,840-foot (870 m) summit at the western edge of the White Mountains.

In 1920 a report was issued on the state forest area that was then 343 acres (139 ha) and included a Black Mountain Lookout Station (no longer present).

It was composed of pasture and young spruce.
