Big Level is an unincorporated community in Stone County, Mississippi, United States.

The name Big Level was derived when a broad area of flat terrain was revealed during removal of the vast pine forests, beginning in the late 1800s.

[3] The soil is fertile agricultural land that supported many small family farms and rural neighborhoods before World War II.

In the latter half of the 20th century, residents began taking jobs in towns and cities near the Mississippi Gulf Coast and commuted to and from work.

Within the Big Level area, the communities of Wisdom and Mentorum had post offices in operation from the early 1890s until they closed around 1916; mail was then routed through Wiggins or Perkinston.
