Catharina "Kaatje" van Dam-Groeneveld (20 November 1887 - 16 February 2001) was a Dutch supercentenarian, who was the first Dutch person to celebrate her 112th and 113th birthdays, thereby extending the Dutch longevity record from 111 to 113 years; later, her age would be surpassed by Hendrikje van Andel-Schipper.
