The stigma of men’s mental illness has been described as having wide-reaching and profound consequences beyond the condition[s] itself. Stigma negatively impacts men’s mental health help-seeking and the use of services amid impeding disclosures, diminishing social connection and amplifying economic hardship. Although men often face barriers to discussing their struggles with, and help-seeking for mental illness challenges, research focused on men’s lived experiences of mental illness stigma is, at best, emergent. This scoping review explores men’s mental illness related stigmas synthesizing and discussing the findings drawn from 21 published qualitative articles over the last 10 years. Four thematic findings were derived: (a) the weight of societal stigma, (b) stigma in male-dominated environments, (c) inequity driven stigmas, and (d) de-stigmatizing strategies. Despite evidence that stigma is a common experience for men experiencing diverse mental illness challenges, the field remains underdeveloped. Based on the scoping review findings, research gaps and opportunities for advancing the field are discussed.
