King Abdulaziz Historical Center (KAHC) (Arabic: مركز الملك عبدالعزيز التاريخي) is a cross-district heritage complex in Riyadh, Saudi Arabia, covering south of al-Murabba and north of al-Futah.

Inaugurated in 1999, it includes several historic buildings and open green spaces that surround the Murabba Palace compound, which was the main residence and workplace of King Abdulaziz ibn Saud between 1938 and 1953.

The surrounding area was made into a landscape of parks and plazas and new buildings were built such as the National Museum of Saudi Arabia.

On the east side the new National Museum of Saudi Arabia was built together with the King Abdul Aziz Foundation for Research and Archives.

To the south, the area around the old water tower has been remodelled and now includes a small theme park.
