Kingdom Centre, formerly Kingdom Tower, is a 99-story, 302.3 m skyscraper in Riyadh, Saudi Arabia. When completed in 2002, it overtook the 267-meter Faisaliyah Tower as the tallest tower in Saudi Arabia. It has since been surpassed and, as of 2021, is the fifth-tallest skyscraper in the country, whose tallest two buildings are the Abraj Al Bait Towers and the Capital Market Authority Tower.

The tower was developed by Prince Al-Waleed bin Talal and designed by the team of Ellerbe Becket and Omrania, who were selected through an international design competition. It is situated on a 100,000–square-meter site and houses the 57,000-square-meter Al-Mamlaka shopping mall, offices, the Four Seasons Hotel Riyadh, and luxury apartments. There is a 65m skybridge atop the skyscraper.

The King Abdullah Mosque on the 77th floor of the Kingdom Centre building in Riyadh, Saudi Arabia, is 183 m above ground level and was completed on 5 July 2004. The mosque is open to the public for prayers at the requisite times and has a caretaker. There is an area designated for washing and ablutions and it is marked as a mosque from the outside.
