King Abdullah Park, formerly Al-Malaz Square is an equestrian field-turned municipal park in the al-Malazz neighborhood of Riyadh, Saudi Arabia, located adjacent to Prince Faisal bin Fahd Stadium. Covering an area of 31.8 hectares (79 acres), the square served as a horse racecourse from the early days of Saudi Arabia's establishment till 2002, before being reopened as the largest public park in the country in 2013.

Popular for its 12-meter wide pedestrian corridor, 110-meter giant laser fountains and an artificial lake, the park gets flooded by visitors during festive seasons of Eid al-Fitr, Eid al-Adha and publicly organized events such as the Saudi National Day where the park also displays fireworks before midnight.
