Jean-Frédéric Osterwald (or Ostervald) (25 November 1663 – April 14, 1747), Swiss Protestant pastor, was born at Neuchâtel in 1663 in a patrician family, a son of the Reformed pastor Johann Rudolf Ostervald. He was educated at Zürich and at Saumur (where he graduated), studied theology at Orléans under Claude Pajon, at Paris under Jean Claude and at Geneva under Louis Tronchin, and was ordained to the ministry in his native place in 1683.

Ostervald's French Bible, a revision of the French translation, in particular, was long well known and much valued in Britain.
