Louisa Ann Swain (née Gardner; 1801 – January 25, 1880) was the first woman in the United States to vote in a general election after the repeal of women's suffrage in New Jersey in 1807.

She stayed with them until 1820, then moved to Baltimore where a year later, she married Stephen Swain, who operated a chair factory.

They had four children, and in the 1830s, Stephen sold his business, and the family moved, first to Zanesville, Ohio, and later to Richmond, Indiana.

[4] Stories differ on Swain's movements on September 6, 1870, before she voted in that year's primary election.

[5] A widely-circulated story is that she arose early, put on her apron, shawl and bonnet, and walked downtown with a tin pail to purchase yeast from a merchant.

Soon after the election, Stephen and Louisa Swain left Laramie and returned to Maryland to live near one of her daughters.
