The present invention relates to a nozzle for a combustor and a gas turbine including the same. The nozzle for the combustor according to one aspect of the present invention comprises at least one cluster composed of a plurality of tubes through which an air and a fuel move. The cluster may include: a main tube through which the air and the fuel move; a sub tube disposed surrounding the main tube; a fuel supplying unit located at the main tube interior, and supplying the fuel; and a plurality of blade units which protrude radially from the fuel supplying unit, wherein one side end part is coupled to the fuel supplying unit, and wherein the other side end part contacts the inner peripheral surface of the main tube. Provided are the nozzle for the combustor, capable of supplying the fuel to the tube center, and the gas turbine including the same. 본 발명의 일 측면에 따른 연소기용 노즐은, 공기와 연료가 이동하는 복수의 튜브로 구성된 적어도 하나 이상의 클러스터를 포함하며, 상기 클러스터는, 상기 공기와 상기 연료가 이동하는 메인 튜브, 상기 메인 튜브를 둘러싸며 배치된 서브 튜브, 상기 메인 튜브 내부에 위치하여, 상기 연료를 공급하는 연료 공급부 및 상기 연료 공급부로부터 방사상으로 돌출되며, 일측 단부는 상기 연료 공급부에 결합되고 타측 단부는 상기 메인 튜브의 내주면에 접촉하는 복수의 날개부를 포함할 수 있다.
