Meisterstück (German for masterpiece) is the flagship line of pens from luxury brand Montblanc.

Although principally concerned with writing instruments, the brand has of late used the Meisterstück name in association with members of its diversified product range including watches, jewelry and leather goods.

The first Montblanc to be branded a Meisterstück was produced in 1924to denote the then Simplo company's top-line range of writing instruments.

Beginning initially with Safety Filling pens, the Meisterstück name continued to denote the company's top line of writing instruments bearing warranted nibs and offering higher grade features than other models, such as the incorporation of celluloid and precious metals.
