Ronald H. Miller (April 17, 1938 – May 4, 2011) was professor of the Religion Department at Lake Forest College in Illinois.

He was a co-founder and co-director of Common Ground, an active adult education group for interfaith study and dialogue founded in 1975.

Miller was vice-president of the Interreligious Engagement Project 21 and board member at Hands-of-Peace, an organization that brings American, and Palestinian and Israeli teenagers from the Middle East together for a two-week program in the United States.

Miller lectured at countless churches, temples, mosques and centers across the country and wrote books aimed at a popular audience that convey contemporary issues in New Testament studies as well as in spirituality and philosophy.

Miller's body was cremated and his ashes spread by a particular tree near his former office at Lake Forest College, as per his wishes.
