George Knox Shiel (c. 1825 – December 12, 1893) was an American lawyer and politician who served one term as a Democratic U.S. congressman from Oregon from 1861 to 1863.
Born on the island of Ireland (the entirety of which was then part of the U.K.) in 1825, Shiel migrated to the United States and settled in New Orleans.
He was nominated for colonel of Marion County at the 1856 Oregon Democratic Convention, and though it is unlikely he commanded any troops, he kept the title until his death.
[1] In June 1860, Shiel was elected as a Democratic United States Representative for Oregon's at-large district.
Though the bills were never reconciled or signed into law, another election was held nonetheless, and was won by Andrew J. Thayer.
