Gerhard Charles Aalders (25 March 1880 – 30 January 1961), usually styled as G. Ch. Aalders, was a Dutch Old Testament scholar. He was born in London to an English mother and a Dutch father. He served as a minister of the Reformed Churches in the Netherlands from 1903 to 1920, and as Professor of Old Testament at the Free University of Amsterdam from 1920 to 1950.
Aalders is best known for his books A Short Introduction to the Pentateuch (which I. Howard Marshall says kept him going during his student days) and The Problem of the Book of Jonah. He also wrote a number of commentaries in the Korte Verklaring series: Genesis, Daniel, Esther, Jeremiah, and Lamentations.
George Harink suggests that, along with Seakle Greijdanus, F. W. Grosheide, and Jan Ridderbos, Aalders "took the lead in Neo-Calvinist exegetical production."
