Leavittsburg (/ˈlɛvɪtsbɜːrɡ/ LEV-its-burg[4]) is a census-designated place in Trumbull County, Ohio, United States.

Located directly west of Warren, Ohio, it is part of the Youngstown–Warren metropolitan area.

(Leavitt and Suffield businessmen Oliver Phelps, Gideon Granger, Luther Loomis and Asahel Hatheway owned between them one-quarter of all the lands in the Western Reserve assigned to Connecticut.

[6][7] Leavitt had a fleet of ships that traded as far afield as the British West Indies and was a selectman for the town of Suffield.

The resulting volume was entitled A Tour to New Connecticut in 1811, and was published later after the manuscript was discovered in the Yale University library.

Author Washington Irving accompanied Ellsworth on a subsequent trip over 20 years later, calling his journal A Tour on the Prairies.

A post office with the name Leavittsburgh was established March 15, 1864; the spelling was amended to Leavittsburg with effect from July 19, 1893.
