Petrus Hofstede de Groot (8 October 1802 - 5 December 1886), Dutch theologian, was born at Leer in East Friesland, and was educated at the Gymnasium and University of Groningen.^[1]

For three years (1826-1829) he was pastor of the Reformed Church at Ulrum, and then entered upon his lifelong duties as professor of theology at Groningen. With his colleagues Louis Gerlach Pareau, Johan Frederik van Oordt, and Willem Muurling, he edited from 1837 to 1872 the Waarheid in Liefde. In this review and in his numerous books he vigorously upheld the orthodox faith against the Dutch "modern theology" movement. He became professor emeritus in 1872, and died at Groningen on 5 December 1886.^[1]
