Evan Alfred Evans (March 19, 1876 – July 7, 1948) was a judge of the United States Court of Appeals for the Seventh Circuit from May 17, 1916, until his death.
Born in Spring Green, Wisconsin, Evans received a B.A. from the University of Wisconsin–Madison in 1897 and an LL.B. from the University of Wisconsin Law School in 1899. He then practiced law in Baraboo, Wisconsin, from 1900 until his nomination by President Woodrow Wilson on May 1, 1916, to a seat on the United States Court of Appeals for the Seventh Circuit vacated by William Henry Seaman. He was confirmed by the United States Senate on May 10, 1916, and received his commission the same day. After 1936 he was the court's senior active judge (the title "chief judge" was created for the senior judge of a circuit Court of Appeals just after his death), and after 1939 he was the longest-serving active circuit judge in the nation. His record as longest-serving active judge on the Seventh Circuit stood for fifty years.
