Þorlákshafnarprestkall is a Lutheran (Church of Iceland) parish in southern Iceland, located within Árnessýsla. It is part of the Suðurprófastsdæmi (Southern Federation of Parishes).
Þorlákshafnarprestkall administrates three parish churches: Þorlákskirkja, Hjallakirkja, and Strandarkirkja, the latter two having been absorbed into the parish due to the lack of population within them.
