National Day (Arabic: اليوم الوطني‎‎; Yawm al watani) is celebrated on December 2 each year in the United Arab Emirates. It marks the UAE's formal nationalisation from the British Protectorate Treaties which ended on December 1, 1971 and the eventual, federal unification of the seven emirates in 1971 which combined to form the modern-day country, headed by Sheikh Zayed bin Sultan Al Nahyan, the federation's first president. Grand celebrations are held across the country to mark the event.

There are several activities conducted all over the emirates to mark this auspicious event. Fireworks, Car Rallies and Dance Shows are the most common activities. Heritage Villages are set all over the emirates in order to celebrate this event traditionally. Holidays are given from the National Day until 2 days later. Air Shows are conducted on Abu Dhabi and Ajman Corniche while Military Processions are held at Abu Dhabi National Exhibition for the Rulers of the Emirates, Members of the Federal National Exhibition and the Emirati Citizens.
