Robert Lettis Hooper Jr (c.1730 – July 30, 1797) was a soldier in the American Revolutionary War, later a member of the New Jersey Legislative Council, of which he was Vice President.
His great-grandfather Daniel Hooper, a native of Barbados, was a judge in Elizabethtown and Newark, and was of the East New Jersey Provincial Council.
Although this position never materialized, it led to Hooper being appointed by Governor William Franklin to report on the country he had surveyed.
On July 15, 1780, Congress, found military "posts without troops there stationed and in the Continental service" burdensome and expensive, and reorganized the Quartermaster's Department, legislating Hooper out of office effective August 1.
On September 24, 1783, Hooper Jr was elected an honorary member of the New Jersey Society of the Cincinnati, along with William Livingston, Elias Boudinot and Thomas Henderson.
One son, Robert Lettis Hooper, was born on July 2, 1788, but died in 1790, being buried at Christ Church, Philadelphia, on September 3, 1790.
