John William Ross (March 9, 1878 – July 9, 1925) was a United States federal judge.
Born in Hardin County, Tennessee, Ross received an LL.B. from Cumberland University in 1900. He was in private practice in Savannah, Tennessee, from 1900 to 1913, and was a chancellor of the 8th Chancery District of Tennessee from 1913 to 1921.
On May 26, 1921, Ross was nominated by President Warren G. Harding to a seat on the United States District Court for the Western District of Tennessee vacated by John E. McCall. Ross was confirmed by the United States Senate on May 31, 1921, and received his commission the same day. Ross served in that capacity until his death, in 1925.
