Provided are a hybrid substrate, a semiconductor package including the same, and a method for fabricating the semiconductor package. The hybrid substrate may include an insulation layer, and an organic layer. The insulation layer may include a top, a bottom opposite to the top, and a conductive pattern having different pitches. The organic layer may be connected to the bottom of the insulation layer, and may include a circuit pattern connected to the conductive pattern. The conductive pattern may include a first metal pattern, and a second conductive pattern. The first metal pattern may have a first pitch, and may be disposed in the top of the insulation layer. The second conductive pattern may have a second pitch greater than the first pitch, and may be extended from the first metal pattern to be connected to the circuit pattern through the insulation layer.
