Kingsville is a semi-rural, unincorporated community and census-designated place in Baltimore County, Maryland, United States.

King, a native of Willistown Township, Chester County, Pennsylvania, acquired some 290 acres (1.2 km2) of land from Thomas Kell (a county judge) in and about the site of Kingsville from parts of the original grants of Leaf's Chance, William the Conqueror, Selby's Hope, John's Delight and Onion's Prospect Hill, according to a deed executed May 13, 1816.

King lived in the old Hugh Deane-John Paul mansion (later known as the Kingsville Inn and presently as the Lassahn Funeral home on Belair Road) with his wife Elizabeth Taylor, a sister of the Hon.

John Taylor of Willistown, who settled in the West and was the Chief Judge of the Superior Court of Mississippi for a number of years.

The King family operated a tavern according to an 1847 advertisement in American Farmer (a pioneer agricultural journal) at the forks of Bel Air and Joppa (presumably present day Jerusalem) roads.
