A curved surface forming method of a steel plate for a ship using a mold-less multi-point press is provided to maintain a regular quality of the steel plate by performing a same process for each steel plate. A curved surface forming method of a steel plate for a ship using a mold-less multi-point press includes the steps of defining a dimension and physical characteristics of the steel plate(S10), defining a target curved surface according to a design of the ship(S20), determining relative distance between the target curved surface and the steel plate(S30), performing carbonic large deformation non-linear limited element analysis(S40), determining alignment of each punch(S50), analyzing relation between permanent deformation and elastic deformation of the steel plate on each punch(S55), determining a relation between load-displacement on each punch based on the analyzed relation(S60), processing the steel plate as the target curved surface by using the mold-less multi-point press(S70), and measuring the processed steel plate(S80).
