William Minor Lile (March 28, 1859 – December 13, 1935) was an American law school professor and administrator.

A graduate of the University of Virginia School of Law, he began teaching at that institution in 1893.

Along with Charles A. Graves and Raleigh C. Minor, he worked to modernize the school, requiring two years of undergraduate study for admittance and increasing the length of instruction from one to three years.
