This note outlines a novel approach to the construction of quantum field theories on four-dimensional Minkowski space, which is based on operator-algebraic techniques. It is explained how Rieffel deformations can be used to deform quantum field theories in a manner which is compatible with Poincar ́ covariance and locality.
