Margaret Hill Morris (November 2, 1737 – October 10, 1816) was a Colonial American Quaker medical practitioner and diarist.

Her journal provides a first hand account of events of the American Revolutionary War in and around Burlington, New Jersey, including the 1776 Battle of Trenton.

[2] She was the daughter of Richard Hill, a Quaker doctor, merchant, amateur botanist, and slaveholder, and Deborah Moore, granddaughter of Lieutenant Governor Thomas Lloyd.

In 1770, she relocated to Burlington, New Jersey near her sister, Sarah Hill Dillwyn, purchasing a house on the Delaware River formerly belonging to Governor William Franklin.

[2][5][6] Though she had wealthy relations she could seek assistance from, Morris desired self-sufficiency and planned "getting into a little business", opening a medical and apothecary practice in 1779.
