George Augustus Waggaman (1782 – March 31, 1843) was a United States Senator from Louisiana.

He served in the War of 1812 under General Andrew Jackson at New Orleans and settled in Baton Rouge, Louisiana, commencing the practice of law in 1813.

Waggaman was elected as an anti-Jacksonian to the U.S. Senate to fill the vacancy caused by the resignation of Edward Livingston and served from November 15, 1831, to March 4, 1835.

He resumed the practice of law in New Orleans and again engaged in sugar cane planting.

In 1840, Waggaman's daughter Christine eloped with a young Canadian lawyer, John Sandfield Macdonald, who made regular trips to Washington on behalf of the government of Upper Canada as Queen's messenger.
