Oscar Richard Hundley (October 30, 1855 – December 22, 1921) was a United States federal judge.
Born in Limestone County, Alabama, Hundley received an LL.B. from Vanderbilt University in 1877. He was in private practice of law in Huntsville, Alabama from 1878 to 1907, serving as a division counsel to the Nashville, Chattanooga and St. Louis Railway from 1884 to 1907. He was a City attorney of Huntsville, Alabama from 1886 to 1890. He was a member of the Alabama House of Representatives from 1886 to 1890, and of the Alabama State Senate from 1890 to 1898. From 1906 to 1907, he was an Assistant U.S. Attorney for the Northern District of Alabama.
Hundley received a recess appointment from President Theodore Roosevelt on April 9, 1907, to a new seat on the United States District Court for the Northern District of Alabama created by 34 Stat. 931. He was formally nominated on December 3, 1907, but his nomination was not confirmed by the United States Senate, and his service was terminated on May 30, 1908. Roosevelt immediately reappointed Hundley to the court by recess appointment, and again formally nominated him on December 8, 1908. The Senate again declined to confirm Hundley, and his second appointment expired on March 3, 1909. Roosevelt's successor, William Howard Taft, gave Hundley yet a third recess appointment to the court on March 6, 1909, but Hundley resigned on May 25, 1909, with no formal nomination having been submitted.
Hundley was thereafter President and general counsel, Sun Life Insurance Company, Birmingham, Alabama, in 1913. He died in Birmingham, Alabama, in 1921.
