The Prince of Wales and Duchess of Cornwall are to visit Pakistan at the end of October, royal officials say.
Charles and Camilla visited India earlier in the year
Charles and Camilla's five-day trip is due to take in Islamabad and rural areas, including some affected by last year's earthquake.
The tour will focus on UK-Pakistan "partnership" and highlighting shared heritage and community links.
It will be the first time the couple have visited Pakistan together and their third joint overseas tour.
The royal couple are scheduled to arrive in Pakistan on 29 October and depart on 3 November.
Specific themes of the trip will be "inter-faith issues, education, youth entrepreneurship and sustainable development", a statement from Clarence House, the official London residence of the royal couple said.
Security for the couple will be tight in a country with a history of violent attacks.
"There is a high threat from terrorism and sectarian violence throughout Pakistan," the British Foreign Office advises on its website.
Charles and Camilla visited Pakistan's neighbour India in March.
