Judson Canfield (January 24, 1759 – February 5, 1840) was a Connecticut state legislator and state court judge.
Born in New Milford, Connecticut, Canfield graduated from Yale College in 1782,[1] and was admitted to the bar in 1785. He entered into private practice in Sharon, Connecticut.[2] He was elected to the Connecticut General Assembly in 1802, and served until 1809, thereafter serving in the Connecticut State Senate from 1810 to 1815.[1] He simultaneously served as a county court judge for Litchfield County, Connecticut, from 1808 to 1815.[1] [2]
Canfield "was one of the purchasers of the school lands in Ohio",[2] and the village of Canfield, Ohio, county seat of Mahoning County, Ohio, was named after him, commemorating his role as a land agent.[2] [3]
Canfield died in New York City,[2] at the age of 81.
