Abstract: We compute exactly the many-point correlation functions formed by arbitrary number of spins, disorder variables, fermion operators, energy-density operators and components of the stress tensor for the planar Ising model in the absence of a magnetic field for T < Tc and T > Tc. It is shown that these correlation functions near the critical point have a scaling form. The scaling functions have been obtained as an expansion suitable for studying large distances between points. The asymptotic behaviour of the scaling correlation functions for distances R ↫ ξ (where ξ is the correlation radius) is determined.
