Introduction: The modern use of the word paradigm began with the theoretical ideas of Thomas Kuhn and then the scientific revolution occurred. Paradigm is a set of concepts accepted by scientists in their study area and provides a framework in which scientists can solve scientific problems. Paradigm is what separates science from nonscience. Method: This review was undertaken by library studies using databases such as CINHAL, Proquest, Science direct, Magiran and SID. Results: Nursing paradigm, like the foundation of a building, determines the goals and boundaries of nursing. In nursing, paradigm is based on shared values, and assumptions related to key concepts such as the individual, health, environment, and nursing. The boundaries of key concepts are reflected in teaching or nursing culture, work experiences, and values which affect our observations of events and situations. These are the foundation for creating the key concepts of nursing. Conclusion: Some believe that nursing may not have a normal science period therefore, they believe it is in its paradigm period. Others believe that if we accept that nursing is in the preparadigm stage then it cannot be considered a science therefore, because it has a philosophy and is a science it is in the paradigm stage.
