The Duke and Duchess of Sussex will make an official visit to Australia, Fiji, the Kingdom of Tonga and New Zealand.
Harry and Meghan's autumn tour - the first announced since the couple tied the knot last month - falls on the occasion of the fourth Invictus Games, which will be staged in Sydney in October.
The couple have been invited to visit Australia and New Zealand by the countries' governments, while the pair will visit Fiji and Tonga at the request of the Foreign and Commonwealth Office, Kensington Palace said.
The official royal tour will be a rite of passage for royal newcomer Meghan as she settles into married life with Harry.
On Saturday she wowed the crowds at her first Trooping of the Colour .
All eyes will be on her as she gets to grips with becoming one half of a royal tour double act, with daily engagements, tree planting and ubiquitous unveiling ceremonies all possibilities on the itinerary.

Harry and Meghan will be following in the footsteps of his parents, the Prince of Wales and Diana, whose first royal tour as a married couple was also to Australia and New Zealand.
During that trip, Charles and Diana travelled 23,601 miles and spent 41 days overseas.
In April 2014, the Duke and Duchess of Cambridge went to Australia and New Zealand, and the pair were away for 18 days, covering 23,701 miles.
