The 1970 Italian Open also known as the Italian Open Championships was a combined men's and women's tennis tournament that was played on outdoor clay courts at the Foro Italico in Rome, Italy. The men's tournament was initially part of the Grand Prix circuit but was withdrawn during the tournament when it became known that the organizers had paid management fees to the competing World Championship Tennis (WCT) organization in order for the WCT players to participate.{{cite book|title=World of Tennis '71|year=1971|publisher=Queen Anne Press|location=London|isbn=978-0-362-00091-7|editor=John Barrett|pages=125–128, 133}} The women's tournament was a non-tour event, i.e. not part of the Virginia Slims Circuit.
