Reyer Jacobsz van Blommendael was a Dutch Golden Age painter from Haarlem.

He entered the Haarlem Guild of that city in 1662, and was buried in the St. Bavochurch there where later his sister Risje (who had previously named him in her will) was also buried. His sister's will from 1669 stated that he was living in Amsterdam, and her newer will from 1675 mentions him living in the Hague.

His works were attributed by Johannes Vermeer, Dirck van Baburen, Cesar van Everdingen, Abraham Bloemaert, Jan van Bronchorst and Gerard van Honthorst.
