Hermleigh lies on U.S. Route 84, ninety-six miles southeast of Lubbock, and has a population of 383 people at the 2020 census.

[5] According to the United States Census Bureau, the CDP has a total area of 9.1 square miles (23.5 km2), all land.

Hermleigh's history begins in 1907 when a townsite was surveyed on land donated by two men named R. C. Herm and Harry W. Harlin near the small community of Wheat.

The Roscoe, Snyder and Pacific Railway was built through the new community, and residents of Wheat began to relocate to Hermleigh.

In 1911 the Santa Fe Railroad reached the community, and Hermleigh developed into a shipping point and trading center for local ranchers and cotton farmers.

A school opened to serve area students in 1913, and by the late 1910s the community had its own newspaper (the Hermleigh Herald).

Hermleigh briefly changed its name in the late 1910s to Foch to honor the French field marshal and World War I hero Ferdinand Foch, but reverted to the original name shortly thereafter and continued to flourish until the early 1930s, when the effects of the Great Depression brought an end to Hermleigh's growth.
