Aldwick is a seaside village and civil parish in the Arun district of West Sussex, England.

The ecclesiastical parish, formerly part of Pagham[3] includes the smaller settlement of Rose Green.

Aldwick was formerly part of the older Pagham parish and formerly an important tithing, giving its name to a hundred.

Aldwick had, briefly, a home of the constitutional monarch of the British Empire when King George V convalesced (with his wider family regularly visiting) at Craigweil House in 1929, before its demolition.

A blue cedar Cedrus atlantica (glauca) was planted by Queen Mary in 1929.
