Abstract: Motivated by deformation quantization we investigate an algebraic GNS construction of *-representations of deformed *-algebras over ordered rings and compute their classical limit. The question whether a GNS representation can be deformed leads to deformation of positive linear functionals. Various physical examples from deformation quantization like the Bargmann-Fock and the Schrodinger representation as well as KMS functionals are discussed.
