Reinier van Oldenbarnevelt, lord of Groeneveld, (also known as Reinier van Groeneveld) (c. 1588 – 1623) was the son of Johan van Oldenbarnevelt.

In 1607 he visited Paris with his brother Willem van Oldenbarnevelt as part of their Grand tour, and they were received at the court of king Henry IV of France.[1]

He married Anna Weytsen, lady of Brandwijk and Gijbeland, in Delft in 1608. They had three children;

• 1. Jacoba Francina (1610),
• 2. Johan (1612) and
• 3. Jacob van Oldenbarnevelt (1614).

Reinier became forester of Holland and lived in the Slot Teylingen at Voorhout[2].

After the execution of his father, Reinier conspired with his brother Willem van Oldenbarnevelt and amongst others the Remonstrant preacher Hendrick Danielsz Slatius to assassinate stadtholder Maurice of Orange. The assassination attempt failed however, and Reinier van Oldenbarnevelt was beheaded in 1623 in The Hague for financial complicity in the conspiracy to assassinate prince Maurice.

His wife Anna remarried in 1625 with Jacob Westerbaen.
