Rahi Yar Khan or Rahimyar Khan () is a city in the south of Punjab province in Pakistan. The previous name of the city was Naushehra which was built as a castle in 1750 by Fazal Elahi Halani on the ruins of the ancient Pul-Wadda. Pul-Wadda had been built during the Sumra rule of Sindh. Most notably the former President of the UAE, Sheikh Zayed bin Sultan Al Nahayan had a residence built for him just outside the city, and is called 'Desert Palace' or Abu Dhabi Palace. It is now owned by his son and successor Sheikh Khalifa bin Zayed Al Nahayan.
