John Ripin Miller (May 23, 1938 – October 4, 2017) was an American politician who served as a member of the United States House of Representatives from 1985 to 1993.

Miller led the Council in rejecting Seattle's entry into Washington Public Power Supply System nuclear plants 4 and 5 (Satsop nuclear power plant) which later went bankrupt, and unsuccessfully sought the demolition of the Alaska Way Viaduct separating Seattle's downtown from its waterfront.

Miller served as the director, Office to Monitor and Combat Trafficking in Persons for the U.S. State Department, with the rank of Ambassador-at-Large, starting in 2002.

He sought to increase public awareness of modern-day slavery and nurture a worldwide abolitionist movement with the United States in the lead.

Prior to his time at State, he had served as the chair of the institute, and was an English teacher at Northwest Yeshiva High School in Mercer Island, Washington.
