Kasumi Ishikawa (石川佳純,Ishikawa Kasumi; Yamaguchi, 23 februari 1993) is een Japans tafeltennisspeelster. Ze werd op de WK van 2007 de jongste sportster ooit die Japan vertegenwoordigde op een officieel WK, toen ze in Zagreb uitkwam in zowel het dubbelspel- als gemengd dubbel-toernooi. De linkshandige Japanse speelt sinds het Japan Open van 2006 tegen volwassen opponenten op de ITTF Pro Tour en won daarop in juli 2010 haar eerste enkelspeltitel, die van de Marokko Open.
Ishikawa bereikte in maart 2010 haar tot dan toe hoogste positie op de ITTF-wereldranglijst, toen ze daarop 25e stond.
