Jacques Christian or Jacob Christiaan Pielat (sometimes Pielaat) (27 August 1692, Rotterdam – c. 3 August 1740, Loosduinen) was the 22nd Governor of Ceylon during the Dutch colonial time from 2 December 1732 until 27 January 1734.
After a period of being secunde ("vice-governor") in Ternate, he succeeded Stephanus Versluys as governor of Amboina from 1728–29 to 1731.
After his term as governor he left the customary "memoir" for his successor, Diederik van Domburg,[4] and returned to the Netherlands where he would die 8 years later.
In 1719, Everard Kraeyvanger wrote a poem for Amaranta in consolation for the loss of two of her children in Batavia.
[5] His surviving son Diederik Christiaan would become mayor of Schiedam.
