The Duke and Duchess of Sussex visited Los Angeles National Cemetery to mark Remembrance Sunday.
The couple laid flowers at the gravesites of two Commonwealth soldiers.
The Duke and Duchess also placed a wreath at an obelisk in the cemetery that features a plaque inscribed 'In Memory of the Men Who Offered Their Lives In Defense Of Their Country'.
During their visit to the cemetery, Harry wore a navy suit with his service medals attached.
A spokesman for the couple said: "It was important to the duke and duchess to be able to personally recognise Remembrance in their own way, to pay tribute to those who have served and to those who gave their lives."
Prince Harry served in the British Army for a decade, including tours of Afghanistan.
In previous years, the Duke has marked Remembrance with visits to the Cenotaph and Westminster Abbey’s Field of Remembrance.
