Correlates of past-year suicidal ideation and lifetime suicide risk among a national sample of transgender veterans were examined. An online, convenience sample of 212 U.S. transgender veterans participated in a cross-sectional survey in February–May 2014. We evaluated associations between sociodemographic characteristics, stigma, mental health, and psychosocial resources with past-year suicidal ideation and lifetime suicide plans and attempts. Participants reported high rates of past-year suicidal ideation (57%) as well as history of suicide plan or attempt (66%). Transgender-related felt stigma during military service and current posttraumatic stress disorder and depressive symptoms were associated with suicide outcomes as were economic and demographic factors.
