Solomon Southwick (December 25, 1773 – November 18, 1839) was an American newspaper publisher and political figure who was a principal organizer of the Anti-Masonic Party.

After the Anti-Masons were supplanted by the Whigs as the major alternative to the Democratic Party, Southwick decided to forgo further involvement in politics.

Southwick's father was the publisher of the Newport Mercury newspaper and an ardent supporter of the Patriot cause during the American Revolution.

[7][8] In addition to editing the Albany Register, Southwick became active in civic life and took part in politics as a Democratic-Republican.

He was prosecuted by Thomas Addis Emmet, and defended by Aaron Burr, Daniel Cady, Abraham Van Vechten and Ebenezer Foote.

He then published several specialty newspapers, including The Plough Boy, a publication which provided information about farming in New York and advocated the creation of local, county and state agricultural societies.

He also published and edited the Christian Visitant, a religious magazine, and the National Democrat, a political newspaper which opposed the Democratic-Republicans.

[16][17][18] In addition, Southwick opened an office that organized and operated lotteries to raise money for state projects and programs.

According to Thurlow Weed and other contemporaries, Southwick appeared in the mid-1820s to have become eccentric, and consulted fortune tellers and mystics in an effort to obtain winning lottery numbers for contests held in other states.

He became a popular moralizer and sermonizer on the statewide lecture circuit, and frequently delivered addresses including: The Bible; Temperance; and Self-Education, many of which were also reproduced as pamphlets.
