An electronic package and a method for fabricating an electronic package are provided. An encapsulation layer encapsulates a first electronic component and a plurality of conductive pillars, and is defined with a reservation region and a removal region adjacent to the reservation region. A circuit structure is disposed on the encapsulation layer. The removal region and the circuit structure therewithin are removed for an optical communication element to protrude from a lateral surface of the encapsulation layer when the optical communication element is disposed on the circuit structure, so as to avoid a packaging material used in a subsequent process from being adhered to a protruding portion of the optical communication element.
