Milton H. Hamilton Jr. (September 8, 1932 – September 5, 2008) was a Tennessee politician who served in both houses of the Tennessee General Assembly and was majority leader of the Tennessee State Senate and Tennessee Commissioner of Environment and Conservation.
Hamilton was born in Obion County, Tennessee in 1932. He was educated in the Obion County public schools. He attended Memphis State University (now the University of Memphis) and was graduated with the B.A. degree from Murray State University, where he participated in the ROTC program, in 1955. He immediately afterward fulfilled his commitment to the United States Army, spending two years on active duty as a second lieutenant before being honorably discharged in 1957, although he remained in the Tennessee Army National Guard until 1977.
Hamilton's first elected office was service on the Union City, Tennessee Board of Education. In 1964, he was elected to the Tennessee House of Representatives, where his father had previously served, as a Democrat. Hamilton served two terms in the State House.
In 1968, Hamilton was elected to the state Senate from District 24, representing much of the northern part of West Tennessee. He served in an increasingly important series of positions on committees and in party leadership posts, culminating with his selection as majority leader in 1977, a position which he was to hold for 10 years.
