Cape Jaffa is a headland in the Australian state of South Australia located at the south end of Lacepede Bay on the state's south east coast about 20 km south west of the town centre of Kingston SE. The cape is described as being "a low sandy point" with "its sea face is about 1 nmi long" and having a "wooded range rises near the S[outh] part of the cape and reaches a height of 77 m at Mount Benson, about 8.5 nmi S[outh] E[ast]". A settlement known as King's Camp in some sources and as Cape Jaffa in other sources is located about 0.5 nmi to the north west of the cape. This settlement includes a jetty fitted with a navigation aid and a marina. The southern coastline of the cape forms part of the Bernouilli Conservation Reserve.
