Deera Square (), also known as Justice Square (), is a public space in the ad-Dirah neighborhood of Riyadh, Saudi Arabia, located adjacent to the al-Hukm Palace compound and Imam Turki bin Abdullah Grand Mosque in the Qasr al-Hukm District. It is a former site of public executions, where those sentenced to death in Saudi Arabia were publicly beheaded.
At unannounced times, Saudi security forces and other officials cleared the area to make way for the execution to take place. After the beheading of the condemned, the head is stitched to the body, which is wrapped up and taken away for the final rites. It is a crime to record, with photos or videos, the executions, despite the number of attendees witnessing such public events.
