Saudi Flag Day, officially the Flag Day,[1] is a public holiday in Saudi Arabia observed annually on March 11 to commemorate the adoption of the unstandardized version of the country's national flag by King Abdulaziz ibn Saud in 1937.[2] It was first celebrated on the 86th anniversary of the adoption in 2023,[3] when King Salman bin Abdulaziz designated it as the nation's third non-religious legal holiday to be observed as per the Gregorian calendar after Saudi National Day and Saudi Founding Day.

The flag was in official use for 36 years until 1973 when King Faisal standardized it.[5]
