Abstract: In this article, we consider the best polynomial approximation operator defined on an Orlicz–Lorentz space Λw,ϕ$\Lambda _{w,\phi }$ generated by an Orlicz function ϕ and a non‐negative continuous weight function w. Then we extend the best polynomial approximation operator from Λw,ϕ$\Lambda _{w,\phi }$ to Λw,ϕ′$\Lambda _{w,\phi ^{\prime }}$, where ϕ′$\phi ^{\prime }$ is the derivative function of ϕ. In addition, we establish some properties of the extended best polynomial approximation operator.
