Nicholas Ware (February 16, 1776 – September 7, 1824) was a United States senator from Georgia.

Ware was born in Caroline County, Virginia and later moved with his parents to Edgefield, South Carolina and a few years later to Augusta, Georgia.

That year the Georgia legislature elected him as a Democratic-Republican (later as a Crawford Republican) to the U.S. Senate to fill the vacancy caused by the resignation of Freeman Walker; he served from November 10, 1821, until his death in New York City in 1824.

At the time of the 1820 census, he owned 62 slaves[1] and had extensive plantation near Augusta.

He developed it for cotton, the major commodity crop of the Deep South in the antebellum era.
