Deaths of elderly individuals (60 years or older) with suicide as the underlying cause, according to ICD-10 codes X60-X84, Y10-Y19, and Y87, were included. Segmented linear regression analysis was adopted to calculate the annual percentage variation and significant changes in trend. From 2011 to 2020, there were 1,721 suicide deaths in SC. There was a significant increase in suicide mortality rates among elderly individuals in the state of SC (2016 to 2020) and in the macroregions of Meio Oeste and Serra (2011 to 2020), Grande Oeste (2018 to 2020), and Grande Florianópolis (2016 to 2020). Mortality rates decreased in SC (2011 to 2016) and in the macroregions of Grande Oeste (2011 to 2018), Grande Florianópolis (2011 to 2016), and Foz do Rio Itajaí (2011 to 2020). Suicide mortality rates differ among the macroregions of the state and SC.
