A turbine airfoil with a leading edge cooling air supply channel located along the leading edge region of the airfoil to supply cooling air from an outside source and a series of serpentine flow cooling circuits positioned along the leading edge of the airfoil connected to the cooling supply channel to pass cooling air through the series of serpentine passages in a direction from the airfoil root to the airfoil tip. The series of serpentine circuits includes legs on the pressure side and the suction side of the leading edge. Cooling air from the supply channel is metered into the first leg of the serpentine circuit located near the root, flows through a series of serpentine circuits along the leading edge of the airfoil, and flows out to the tip through a tip hole in the last leg of the last serpentine circuit.
