Dexter Russell Wright (June 27, 1821 - July 23, 1886) was an American lawyer and politician.
Wright was born in Windsor, Vermont, on June 27, 1821, the son of Alpheus and Anna E. (Loveland) Wright. During his boyhood, the family removed to the northern part of New York State, and in 1843 he entered the Junior Class of Wesleyan University, at Middletown, Conn., from Heuvelton, St. Lawrence County.
He graduated in 1845, and then taught for a year in Meriden, Connecticut, after which he attended for two years the courses in the Yale Law School. After earning a law degree in 1848, he opened an office in Meriden, and the next year began his political career by his election to the Connecticut State Senate. After serving one term, he sailed for California, where he spent two years practicing law and in land speculation. He then returned to Meriden, and followed his profession until 1862, when he enlisted in the Union Army. He was a colonel of the 15th Regiment State Volunteers from July 1862 until February 1863 when his health failed and he was honorably discharged.
In 1863 he was a member of the Lower House in the Connecticut Legislature, and from 1863 to 1865 he served as a commissioner on the Board of Enrollment for the 2nd Congressional District. In 1864 he resumed the practice of law, establishing his office in New Haven. He was Assistant U. S. District Attorney from 1865 to 1869, and subsequently held a variety of positions in connection with city government. He was sent as a Representative to the General Assembly in 1879, and was chosen Speaker of the House.
In the spring of 1886 he fell on the steps of his residence, causing a shock to his entire system, from which he only partially recovered. On June 19 he was stricken with paralysis, which resulted in his death in New Haven on July 23, 1886, at the age of 65.
He married Maria on February 3, 1848, who survived him, with two daughters and two sons; the younger son graduated Yale in 1882.
