Thomas Sugden (June 12, 1810 – August 27, 1883) was an English American immigrant, farmer, and Wisconsin pioneer.

In July 1834, he hired out to do haying and harvesting at what was then called "Bay settlement" in the Toledo strip (later to become part of Ohio)[3] In his seven-week absence, a cholera epidemic struck Detroit, and roughly half the population died or left.

He was first appointed a notary public by Governor Nelson Dewey in 1849, and would retain that office through his retirement years.

[6] He was elected as a Whig to the 2nd Wisconsin Legislature (the 1849 session) from Waukesha County's 5th Assembly district (towns of Genesee, Delafield and Pewaukee), succeeding Democrat Joseph Bond.

He would return to the Assembly for the 1852 session, succeeding Democrat Hosea Fuller Jr. in what was now the 3rd Waukesha County district.
