Julius Bodenstab (January 13, 1834 – June 1, 1916) was an American farmer from Howard's Grove, Wisconsin who spent two one-year terms as a Liberal Republican Party member of the Wisconsin State Assembly from Sheboygan County, and later became a real estate broker. He was the father of Henry Bodenstab, who would himself serve two terms in the Wisconsin State Senate.
Bodenstab was born January 13, 1834 in Ronnenberg in the Kingdom of Hanover. He came to the United States in 1846 with his parents; they settled briefly in Albany, New York but in 1847 moved on to Wisconsin, settling in Hermans Grove in the Town of Herman in Sheboygan County. He received a common school and academic education, and became a farmer.
He joined the United States Army during the American Civil War, entering the 27th Wisconsin Volunteer Infantry Regiment in 1862 as a private and mustering out as a first lieutenant in 1865, having participated in the siege and capture of Vicksburg, Little Rock, and Spanish Fort, Alabama.
