Event was due to take place on 1 August
This year's Castletown Festival and Confetti Carnival, due to take place on August 1, has been cancelled.
Organisers say they made the decision due to the current coronavirus pandemic.
Festival Committee Chairman Rachael Keyes said "I know it will be a disappointment for many, especially the children, but the festival will be back bigger and better on August 7 2021".
