Adam E. Ray (1808 - September 20, 1865) was an American farmer from Troy, Wisconsin who served a single term in 1851 as a Free Soil Party member of the Wisconsin State Assembly from Walworth County.
Ray was the son of Martin Ray and Caroline Phelps Ray, born in Kingston, New York in 1808. (His brother George Augustus Ray, who would also serve in the legislature, was born in 1819). Adam Ray came to Milwaukee in Wisconsin Territory around 1837, and represented Milwaukee and Washington counties in the territorial Legislature; lower house from 1839 to 1842; upper house in 1845.
About 1846 he settled in Troy with his wife, Eliza. They would have children: Patrick Henry, Eliza, Mary, Augusta, Jane, Fred, Ira, and Ida. Patrick Henry Ray would retire as a brigadier general; the Ray Mountains and Ray River in Alaska are named after him.
In 1847, Ray was chairman of Troy's town board and a member of the county's Board of Supervisors.
In 1850, he was elected to the Assembly as a Free Soiler for the 1851 session, succeeding Whig Alexander O. Babcock. He was succeeded in 1852 by fellow Free Soiler Stephen Steele Barlow.
In 1851 Ray was a member of the executive committee of the newly organized Wisconsin State Agricultural Society. He served as a judge in two categories of the first Wisconsin State Fair: Merinoes, and flour and corn meal; and took several prizes in farm implements: best , manure fork, grass scythe, grain scythe, and hay knife.
