The invention discloses a turbine blade, a turbine and a turbine blade design method and device.The turbine blade design method comprises the step of designing a wrap angle of a blade outlet section in the axial direction, and the step of designing the wrap angle of the blade outlet section in the axial direction comprises the step of sequentially confirming wrap angle design values in the axis direction. According to the turbine blade design method provided by the invention, wrap angle optimization control in each axial direction is carried out at the outlet section of the blade according to the requirement of a flow field, and meanwhile, when the wrap angle change difference value exceeds the preset position, the preset value of the adjacent wrap angle difference value is taken as the wrap angle value on the corresponding layer of the blade; the condition that the reliability is affected due to the fact that large stress is caused by too large degree change is avoided, and therefore the turbine blade design
