The D.F. Wouda Steam Pumping Station (ir. D.F. Woudagemaal) is a pumping station in the Netherlands, and the largest still operational steam-powered pumping station in the world.

In 1967, after running on coal for 47 years, the boilers were converted to run on heavy fuel oil. It has a pumping capacity of 4,000 m3/min (1,100,000 U.S. gal/min). The pumping station is currently used to supplement the existing pumping capacity of the J.L. Hooglandgemaal in Stavoren in case of exceptionally high water levels in Friesland; this usually happens a few days per year.
