John Rowlett Paine, commonly known as Rowlett Paine, was a Memphis, Tennessee born wholesale grocer and Methodist community leader who served as the 37th mayor of Memphis from 1920 to 1927. A civic-minded reformer, he implemented numerous initiatives aimed at reforming juvenile justice, city zoning, public health, and educational improvements. Initially a strong ally of E.H. "Boss" Crump, sharing the desire to eliminate the local Ku Klux Klan, their eventual disagreements would drive them to be strong political opponents.
