Lyman Hall (April 12, 1724 – October 19, 1790) was an American Founding Father, physician, clergyman, and statesman who signed the United States Declaration of Independence as a representative of Georgia.

His pastorate was a stormy one: an outspoken group of parishioners opposed his ordination; in 1751, he was dismissed after charges against his moral character which, according to one biography, "Were supported by proof and also by his own confession."

He continued to preach for two more years, filling vacant pulpits, while he studied medicine and taught school.

On the eve of the American Revolution, St. John's Parish, in which Sunbury was located, was a hotbed of radical sentiment in a predominantly Loyalist colony.

In 1790, Hall moved to a plantation in Burke County, Georgia, on the South Carolina border, where he died on October 19 at the age of 66.

Lyman Hall is memorialized in Georgia where Hall County, Georgia, bears his name; and in Connecticut, his native state, where the town of Wallingford honored him by naming a high school after its distinguished native son.

Signers Monument, a granite obelisk in front of the courthouse in Augusta, Georgia, memorializes Hall along with Button Gwinnett and George Walton as Georgians who signed the Declaration of Independence.
