Beechgrove, also known as Beech Grove, is an unincorporated community in Coffee County, Tennessee, United States.

[3][4] Beechgrove, Tennessee, was named "Beech Grove," until zip codes were assigned to U.S. Post Offices.

At that time the post office named "Beech Grove" in another county was given its zip code before the Coffee County location received its code; thus to avoid confusion among postal users, and the Postal system itself, Beech Grove (Coffee County), Tennessee was changed, officially, to "Beechgrove."

The community was named from the presence of beech trees near the town site.

The Beechgrove Confederate Cemetery now occupies a portion of the battlefield, on top of a hill overlooking present-day I-24.
