The Society for the Psychological Study of Men and Masculinity, Division 51 of the American Psychological Association, advances knowledge in the psychology of men through research, education, training, public policy, and improved clinical practice.

Division 51 believes aspects of traditional gender roles are restrictive in nature and often lead to negative consequences and unhealthy interactions for many individuals and society. SPSMM endeavors to point out constrictive conceptions of masculinity that have inhibited men's development, reduced men's capacity to form meaningful relationships, and contributed to the oppression of others. SPSMM supports the empowerment of all persons and believes this empowerment leads to the highest level of functioning in individual men and women.
