An object of the present invention is to provide a turbocharger, a turbine nozzle, and a ship that can improve turbine efficiency, and can effectively change an inflow area of exhaust gas that flows into the turbine nozzle according to an engine load. In a turbine nozzle (25), a plurality of blade tip portions (44) are provided spaced apart from each other in a peripheral direction, the blade tip portions (44) being provided between an outer peripheral side member (25b) and a partition member (42), and a plurality of blade root portions (45) are provided spaced apart from each other in the peripheral direction, the blade root portions (45) being provided between an inner peripheral side member (25a) and the partition member (42). Additionally, a trailing edge (45b) of a downstream side in a flow direction of exhaust gas of the blade root portion (45) is formed so as to be located closer to an upstream side in the flow direction of the exhaust gas than a trailing edge (44b) of the blade tip portion (44). Consequently, a throat width (S1) between the blade root portions (45, 45) adjacent to each other in the peripheral direction of the turbine nozzle (25) is set to be larger than a throat width (S2) between the blade tip portions (44, 44) adjacent to each other in the peripheral direction.
