Broer Doekele Dykstra (November 21, 1871 - March 29, 1955), usually cited as B. D. Dykstra, was a Dutch American pastor, educator, and poet who wrote several books, served as editor of the Volksvriend Dutch-language newspaper, and was a visible member of the Reformed Church in America. Known in the RCA as "the man on the bicycle," he operated a small publishing house with his sons and traveled door-to-door to sell his books.

Dykstra was born "Broer Dijkstra" in Pingjum, Friesland in 1871, son of Doekele Dijkstra and Beitske van der Schaaf. The family emigrated to the United States in 1882. He became an avid pacifist.^[1] He was a student at Orange City Academy, now Northwestern College in the late 19th century; today, the school offers the Dykstra-Muste-Nelson Peace Scholarship in his, A.J. Muste's, and Ronald R. Nelson's honor. He died in Orange City, Iowa, United States, in 1955.

Several of his sons became prominent educators and theologians. D. Ivan Dykstra was a professor of philosophy at Hope College, Wesley C. Dykstra held the same position at Alma College, and Vergil Dykstra served as president of George Mason University.
