William Wirt Virgin (September 18, 1823 – January 23, 1893) was an American politician and jurist from Maine.
Virgin was born in 1823 in Rumford, Maine and graduated from Bowdoin College in 1844. He was admitted to the Maine bar in 1847 and moved to Norway, Maine, where practiced law until 1871.[1]
During the American Civil War, Virgin raised the 23rd Maine Volunteer Infantry Regiment, which consisted of five companies from Oxford County and Androscoggin Counties. The Regiment did not see combat, instead acting as a guard of Washington D.C. Virgin, a Republican, served two one-year terms in the Maine Senate (1865, 1866). In his 2nd and final term, Virgin served as the Senate President. In 1872, Virgin was appointed to the Maine Supreme Judicial Court as an associate justice. He served in that position until his death on January 23, 1893.
