A laser cutting nozzle includes an inner nozzle and an outer nozzle. The inner nozzle exhibits a tube shape having a through hole on an axis and having a diameter decreasing on a first end portion side and includes a notch extending in the axis direction along an outer peripheral surface on a second end portion side. The outer nozzle is fitted to the outer peripheral surface of the inner nozzle and includes a vent passage including the notch and communicating between the first end portion and the second end portion in the axis direction. A minimum flow cross-sectional area of the vent passage matches an opening area of the notch in an end surface on the second end portion side.
