Edward George Ryan (November 13, 1810 – October 19, 1880) was an Irish American immigrant, lawyer, and Wisconsin pioneer.

In 1853, he was the prosecutor in the impeachment of Wisconsin Circuit Court Judge Levi Hubbell, on charges of corruption.

Hubbell was acquitted by the Wisconsin Senate, though, later in life, he would be forced to resign his role as a U.S. Attorney due to similar corruption charges.
