The Cornubian Arts & Science Trust (CAST) is an educational charity, inaugurated in 2012 and operating in Cornwall. It aims to promote participation, appreciation and learning in the visual arts and to encourage interdisciplinary dialogue and collaboration across the arts and sciences.

CAST works with artists, curators, writers and specialists from other fields, locally, regionally, nationally and internationally, to develop professional expertise and exchange, to present examples of outstanding creative practice, and to create opportunities for audiences of all ages to experience ground-breaking cultural activity.

CAST is based in Helston, in the former School of Science and Art given to the town by the philanthropist John Passmore Edwards in 1897. Artists have occupied studios in the building since the summer of 2013 and CAST also hosts public activities: workshops, talks, screenings, discussions and summer residencies.

The Trustees of CAST are: Alastair Cameron, Teresa Gleadowe (Chair), Chris Hibbert, Karen Townshend, John Wilkin and Ross Williams.
