Maria Simonis (Sister Antonetta) (born 5 January 1909) is a Dutch supercentenarian whose age is currently unvalidated by the Gerontology Research Group.


Antonetta Maria Simonis was born in The Hague, South Holland, Netherlands on 5 January 1909. Simonis is the first supercentenarian nun from the Netherlands and thus the oldest Dutch nun ever. Currently, she is the second oldest living person in the Netherlands, behind Anne Brasz-Later.

She was confirmed alive on 5 January 2019 by a government official and thus celebrated her 110th birthday. As of today, she still lives in The Hague.
