Christianus Carolus Henricus van der Aa (25 August 1718 – 23 September 1793) was a Lutheran pastor in Haarlem and secretary of the Royal Holland Society of Sciences and Humanities.
Christianus Carolus Henricus was born in Zwolle, where his father Balduinus also worked as a pastor.
On 22 March 1739 he became a Lutheran pastor in Alkmaar, then on 12 August 1742 become a preacher in Haarlem (he had previously been twice, thanks to a job in Gouda).
In Haarlem, at the creation of the Royal Holland Society of Sciences and Humanities in 1752, where he would play a major role, he was appointed as secretary.
Thanks to this he entered into two equally honourable positions, namely at The Hague in 1755 and later in Batavia, Dutch East Indies.
