--- - |2 Abstract Within existing academic literature, ageing within trans populations has primarily been addressed from the perspective of offering advice to service providers and clinicians, with relatively limited application of critical sociological perspectives. This article seeks to integrate the critical perspectives on gerontology with transfeminism, identifying areas of commonality regarding accounts of an integrated lifecourse, scepticism of biomedicalization, and an emphasis on local context. The article suggests that this integration provides a fruitful basis for developing future research into the study of trans ageing, and also provides theoretical development across many debates around age, gender and the lifecourse. - 'The British Journal of Sociology, Volume 70, Issue 4, Page 1490-1509, September 2019.
