James Strohn Copley (August 12, 1916 – October 6, 1973) was a journalist and newspaper publisher. He published the San Diego Union and the San Diego Evening Tribune, both later merged into The San Diego Union-Tribune in 1992, from 1947 until his death in 1973, and was President of the Inter American Press Association (1969 - 1970). His politics was "unabashedly conservative, Republican and pro-American". He had close associations with leading Republican of the era, including Barry Goldwater, Richard Nixon and Spiro Agnew. Copley's presence was a chief reason that the Republican National Convention of 1972 was originally planned to be in San Diego.
