Font Hill Manor is a historic slave plantation in Ellicott City in Howard County, Maryland, USA.

[2] The building was constructed by Admiral Hammond in the 1700s on land originally owned by Charles Carroll of Carrollton.

The Hammond family were prominent in early Maryland government and settled several slave plantations through Anne Arundel and modern Howard County.

The Font Hill property also adjoins the historic Gray Rock slave plantation, once managed by the former county executive, Charles E. Miller.

[6] By 1995, the Font Hill Property had been subdivided and reduced to 3.32 acres, with 36 modern homes built around the manor.
