Hannig, a downstate Litchfield resident, was named by Gov. Pat Quinn in February 2009. He recently was appointed to another two-year term.
Hannig, 58, cites personal and family reasons for leaving, saying, "It is time for me to move on to another phase in my life."
He previously had been a member of the Illinois House since 1979.
