(the "Registrant"), with Carnival plc as the wholly-owned UK subsidiary of Carnival Corporation (the "DLC Unification"). In addition, Carnival Corporation migrated its jurisdiction of incorporation from Panama to Bermuda and changed its name to Carnival Corporation Ltd. (the "Redomiciliation"), and Carnival plc will subsequently be re-registered as a private limited company. This Post-Effective Amendment (the "Post-Effective Amendment") is being filed to deregister any and all securities of the Registrants that remain unsold or otherwise unissued under the Registration Statement (as defined below) and to terminate the effectiveness of the Registration Statement.

·

Registration Statement No. 333-276711 and 333-276711-01 filed with the Commission on January 26, 2024

In accordance with an undertaking made by the Registrants in the Registration Statement to remove from registration, by means of a post-effective amendment, any securities which remain unsold or unissued at the termination of the offering, the Registrants hereby remove and withdraw from registration all securities of the Registrants registered pursuant to the Registration Statement that remain unsold or otherwise unissued as of the date hereof.
