The King Abdullah Mosque (Arabic: مسجد الملك عبدالله), formerly Prince Abdullah Mosque and officially as the Mosque of King Abdullah bin Abdulaziz Al Saud (Arabic: مسجد الملك عبدالله بن عبدالعزيز آل سعود), is a Sunni Islam mosque, in the al-Olaya district of Riyadh, Saudi Arabia, located on the 77th floor of the Kingdom Centre.

[2][3][4][5] It was opened in 2003 and covers an area of 110 square metres (1,200 sq ft).

In 2003, Spazio restaurant was established with assistance from Prince Al Waleed bin Talal on the 77th floor of the Kingdom Centre.

As the number of customers to the restaurant grew, the absence of a place of worship led the administration to build a mosque.

[6] The construction of the mosque was funded by Prince Al Waleed bin Talal.
