The pion nucleon vertex function at finite temperature is studied in two frameworks: (a) the thermal (linear) sigma model to leading (one-loop) order, and (b) a thermal QCD-Finite Energy Sum Rule. Both approaches indicate that the strength of the pion-nucleon coupling decreases with increasing T, va
