+title: Board Vacancies
+link: https://discourse.haskell.org/t/2023-call-for-nominations-for-the-haskell-foundation/5803
+---
+
+The Haskell Foundation [is seeking four new members for the board](https://discourse.haskell.org/t/2023-call-for-nominations-for-the-haskell-foundation/5803). The Board provides the strategic leadership for the Foundation, and is the final decision-making body for everything the Foundation does. More specifically, it ensures that the Foundation is working toward achieving its mission, and it appoints and supervises senior members of Foundation staff.
+
+Nominations are due by March 1, 2023.
