Wilhelm Emil Meerwein (17 September 1844 in Amsterdam – 25 January 1927 in Hamburg) was a German architect and politician.
After further studies in Karlsruhe, where he met his future business partner, Bernhard Georg Hanssen, and at the Bauakademie in Berlin, he briefly worked as a site manager at the Royal Prussian Mint.
Following several study trips, throughout Europe and the Middle East, he settled in Stuttgart in 1871, where he worked with Christian Friedrich von Leins.
In 1899, he was one of the judges in a competition to design a scrapbook for the trading cards that came with chocolates from the Stollwerck company of Cologne.
His fellow judges were Justus Brinckmann, an art director, Georg Hulbe [de], a bookbinder, Julius Christian Rehder (1861–1955), a painter, and Bruno Schmitz, an architect.
