David Jackson (1747 – September 17, 1801) was an American apothecary and physician from Philadelphia, Pennsylvania.

Afterwards he returned to Philadelphia to resume his medical practice and open an apothecary shop.

After the war, Jackson was named as a delegate to the Continental Congress in 1785, and attended the session from April to November that year.

Leaving public service, he also gave up his medical practice and concentrated on his pharmacy business.

David Jr. took over his father's apothecary, while Samuel became a physician and for thirty years was a professor of medicine at the University of Pennsylvania.
