Cornelius Grapheus (1482 – 19 December 1558), Latinized from Cornelis De Schrijver, was a secretary to the city of Antwerp and writer.

His brother was Joannes Grapheus, the printer who also settled in Antwerp.

When Thomas More's Utopia was first printed in 1516, Grapheus provided some liminary verses.

In 1522 he was arrested on accusation of heresy, was taken to Brussels for questioning, and made a full recantation.

In 1540 he was reinstated as secretary to the city, and in 1549 he was again involved in the public welcome of a visiting prince, in this case Philip II of Spain.
