The invention relates to the technical field of ship propulsion systems, and provides a composite thrust bearing and a ship propulsion system.The composite thrust bearing comprises a stator shell, a stator magnetic steel assembly, a rotor magnetic steel assembly, a thrust disc and a thrust pad assembly; the stator shell is used for being arranged on a thrust shaft in a sleeving mode and used for being connected with a ship body. The stator magnetic steel assembly is connected with the stator shell, and the rotor magnetic steel assembly is connected with the thrust shaft; under the condition that the thrust shaft generates axial deviation relative to the stator shell, axial magnetic attraction force is formed between the stator magnetic steel assembly and the rotor magnetic steel assembly; the thrust disc is connected with the thrust shaft; the thrust pad assembly is connected with the stator shell; the thrust pad assembly comprises a first thrust pad and a second thrust pad, the first thrust pad and the first end face of the thrust disc are oppositely arranged in a spaced mode, and the second thrust pad and the second end face of the thrust disc are oppositely arranged in a spaced mode. The composite thrust bearing disclosed by the invention can give consideration to both the axial bearing performance and the axial vibration reduction performance.
