St Alban's Head (corruption of St Aldhelms Head) is a headland located {{convert|5|km|mi}} southwest of Swanage, on the coast of Dorset, England. It is the most southerly part of the Purbeck peninsula, and comprises an outcrop of Portland Stone from the overlying Lower Purbeck Stone. It is part of the Jurassic Coast, a World Heritage Site. It is designated a Special Area of Conservation under the European Union's Habitats Directive.

The Norman St. Aldhelm's Chapel, dedicated to St Aldhelm, Bishop of Sherborne stands on the head. On the bluff of the headland is a monument to the development of radar during World War II, by the Telecommunications Research Establishment at nearby RAF Worth Matravers.{{cite web|url=http://www.purbeckradar.org.uk/memorial/|title=Purbeck Radar|publisher=Purbeck Radar Museum Trust|access-date=20 August 2014}} There is also a coastguard station, now maintained by the National Coastwatch Institution and some former coastguard cottages.{{cite web|url=http://www.nci.org.uk/stalbanshead|title=St Alban's Head - Queens Award for Voluntary Service|date=2012|publisher=National Coastwatch|access-date=20 August 2014}}
