Daniel Chamier (1564–1621) was a Huguenot minister in France, founder of the Academy of Montpellier and author.
Chamier was born at the castle of Le Mont, near Mocas and west of Grenoble. His father was from Avignon and a Protestant convert, a pastor at Montélimar. Daniel studied at the University of Orange and at Geneva under Theodore Beza and Antoine de la Faye (1540–1615), in the period 1583 to 1589. He was ordained minister at Montpellier, and about 1595 succeeded his father at Montélimar.
His provincial synod appointed him deputy to the National Synod at Saumur, and the gathering at Loudun in 1596. He was involved in drafting the Edict of Nantes, and brought the Edict to the Synod of Montpellier in 1598. In 1601 and 1602 he took part in discussions at Montpellier with the Jesuits Pierre Coton and Gaultier. In 1603 he presided over the National Synod at Gap, France, where an article was added to the Reformed Confession of faith declaring the Pope to be the Antichrist.
In 1607 Henry IV of France granted him permission as representative of the Church of Dauphiné to establish an academy at Montpellier, and he became professor there. Chamier returned, however, after a short time to Montélimar. In 1612 he became pastor and professor at Montauban. When Louis XIII besieged the city in 1621, Chamier sent his students to the walls, and was mortally wounded during the defense.
He was married, his wife's name being Portal. They had a son, Adrien, and three daughters.
