Ruben Cornelis Talberg (born 24 August 1964) is an Israeli-German sculptor.

Talberg is known for his Neo-Fluxus Manifolds, which go back to his vision in Bellagio, Italy in the early 1980s.

Talberg's oeuvre deals with antagonistic positions such as Nature & Alchemy, Asymmetry & Dynamics or Eros & Thanathos.

His extensive travels serve as a source of inspiration, providing the foundation for his creative works,referred to as "manifolds."

Talberg's manifolds are represented in more than 200 public and private international collections as well as the auction trade.
