Cockeysville is a census-designated place in Baltimore County, Maryland, United States. Cockeysville was named after the Cockey family who helped establish the town. Thomas Cockey settled in Limestone Valley in 1725 at Taylor’s Hall (an area now just north of Padonia Road and east of Interstate 83). Joshua Frederick Cockey built one of the first homes in the area in 1798 and built the first commercial structure, a hotel, in 1810 in what would become the village of Cockeysville. Cockeysville is home to the Cockeysville Branch of the Baltimore County Public Library and the Historical Society of Baltimore County.
