Creighton C. Hart (February 22, 1906 – March 1, 1993), of Missouri, was a stamp collector and a writer of philatelic articles on specific niches of United States postage stamp collecting.
Unlike some stamp collectors who collect stamps of many countries, Hart restricted his collecting to narrow views of American philately.
He also specialized in collecting covers containing the free franks of American presidents and their widows.
Hart's specialized collections were displayed at various philatelic shows and won many awards.
For many years, Hart was an editor at The Chronicle of U.S. Classic Postal Issues, where he was responsible for editing the 1847-1851 section.
