Although there have been a handful of studies examining the work of chaplains and prison volunteers in a Western setting, few have endeavored to conduct research into the experiences of religious workers in Asian penitentiaries. To fill this gap, this article reports on exploratory research examining the work of a selected group of religious workers in Hong Kong prisons. A total of 17 religious workers were interviewed: 10 prison chaplains and 7 Buddhist volunteers who paid regular prison visits. Qualitative findings generated from in-depth interviews present three themes: the range of religious activities performed, the importance of religion for the rehabilitation of inmates, and the hope of continued religious support to prisoners after discharge. The significance of this research is that it sheds light on the understudied work of prison chaplains and volunteers in Hong Kong and portrays the difference between the works of the Christian ministry and Buddhist volunteers.
