Edwin Eustace Bryant (January 10, 1835 – August 11, 1903) was an American lawyer, Republican politician, and Union Army officer.

[2] With the 3rd Wisconsin Infantry, Bryant participated in many of the significant battles of the eastern theater of the war, including Antietam, Chancellorsville, and Gettysburg.

[5] After re-entering federal service, Colonel Bryant was detailed from his regiment to a military commission—he worked as a judge advocate in Missouri for the next year.

[2] In Madison, Bryant became closely associated with John Coit Spooner and William Freeman Vilas, both of whom later went on to become United States senators.

[2] In 1874, Bryant was the Republican nominee for district attorney of Dane County, but was defeated by the Democratic incumbent, Burr W.

[4] After his term as adjutant general expired in 1882, he was appointed chief clerk of the U.S. House Committee on Public Lands, under the chairmanship of Wisconsin congressman Thaddeus C. Pound, and moved to Washington, D.C. A year later, however, Bryant returned to Madison, purchased a one-third stake in the ownership of the Madison Democrat, and converted his political affiliation to the Democratic Party.
