A gas premix burner and a gas water heater. The gas premix burner has a combustion direction, the gas premix burner can be matched and connected with a premix chamber that is disposed upstream the combustion direction of the gas premix burner, gas and air can be burned by the gas premix burner after mixed in the premix chamber; the gas premix burner comprising: a burner substrate, a main combustion hole provided on the burner substrate; an auxiliary combustion hole disposed downstream the main combustion hole along the combustion direction on the burner substrate; an auxiliary flame of the auxiliary combustion hole intersects a main flame of the main combustion hole. The present application provides the main combustion hole upstream the auxiliary combustion hole along the combustion direction, since the main flame is usually larger in scale than the auxiliary flame, by providing the main flame upstream the auxiliary flame, it will be easier for the auxiliary flame and the main flame to intersect each other, and then the effect of stabilizing the flame is realized by opposed flames formed by the auxiliary flame and the main flame.
