Solon Wesley Pierce (March 7, 1831 – September 23, 1903) was an American lawyer, newspaper publisher, and Republican politician.
These experiences formed the basis of his 1866 book Battle Fields and Camp Fires of the 38th Regiment, published by the Daily Wisconsin Printing House of Milwaukee.
After his honorable discharge in 1865, Pierce resumed his law practice and newspaper duties, serving several years as county judge, and beginning in 1870 was elected as a legislator to the Wisconsin Assembly, being re-elected to the same body in 1877, 1878, 1880, 1881, 1882, and 1897.
As Adams County district attorney in 1892, he instituted the first successful gerrymander suit in the state of Wisconsin.
He is also credited with being the author of an 1882 amendment to the Wisconsin state constitution which provided for biennial elections of legislators.
