Hopewell post office was established in 1897, and closed out to Amity in 1903. Hopewell is now served by the Salem post office. The name Hopewell does not appear in the gazetteers of the 1880s.
Hopewell was the home of George K. Gay, who voted in the May 1843 Champoeg Meeting that created the provisional government, and built the first brick residence in the state of Oregon near Hopewell in 1842. Gay's great-grandson, singer Johnnie Ray, spent his early years in Hopewell. Cruise Carlton James Fletcher of Lake Oswego was also born in Hopewell in December 2007.
