Johan, or Jan van Gool (1685 - 1763) was a Dutch painter and writer from The Hague, now remembered mainly as a biographer of artists from the Dutch Golden Age.
According to the RKD he learned to paint from Simon van der Does and Mattheus Terwesten. He became a member of the Confrerie Pictura in 1711. He was first regent, and then five years later became director, of the Hague Drawing School from 1720-1734. He spent most of his time in the Hague, but travelled to England twice and is recorded there in 1711. He specialized in Italianate landscapes.
He is best known today for his book of artist biographies, otherwise known as the "Nieuw Schouburg". The full title is De Nieuwe Schouburg der Nederlantsche kunstschilders en schilderessen: Waer in de Levens- en Kunstbedryven der tans levende en reets overleedene Schilders, die van Houbraken, noch eenig ander schryver, zyn aengeteekend, verhaelt worden. (The Hague, 1750).
