Jabarkan Persemakmuran dari Kematian dan pemakaman Pangeran Philip, Adipati Edinburgh

Philip was a prominent figure in the Commonwealth of Nations and, particularly, the Commonwealth realms. Representatives of the governments and official oppositions of multiple Commonwealth realms and nations, from throughout his tenure as consort, shared messages of condolences to Elizabeth, and in mourning him for their people as well as the British. Many noted Philip's support and patronage of organisations throughout the Commonwealth, particularly for the Duke of Edinburgh's Award programme. Commonwealth Secretary-General The Baroness Scotland of Asthal also paid tribute, and offered condolences on her behalf.

Flags were flown at half-mast across the Commonwealth to mark mourning and respect for the Duke. The governments of The Bahamas, Canada, and the Solomon Islands issued notices to fly the national flag at half-mast from the announcement of the death to after the funeral and burial. Notices to fly the national flag at half-mast on specific days during the mourning period were also issued by the governments of Australia, Belize, New Zealand, Saint Lucia, and Saint Kitts and Nevis. In Antigua and Barbuda, the flag of the governor-general was flown at half-mast until the day of the funeral.

Physical books of condolences were also opened to the public in some Commonwealth realms; including Government House in Antigua and Barbuda, the Beehive and Tūranga in New Zealand, and Government House in the Solomon Islands. However, physical books of condolences were not opened in Canada, Jamaica, and Australia due to the COVID-19 pandemic.

Gun salutes were fired across the Commonwealth in Philip's honour.
