Map - Salah ad Din Governorate (Muhafazat Salah ad Din)

The Saladin or Salah Al-Din Governorate (محافظة صلاح الدين) is one of Iraq's 19 governorates, north of Baghdad. It has an area of 24363 km2, with an estimated population of 1,042,200 people in 2003. It is made up of 8 districts, with the capital being Tikrit. Before 1976 the province was part of Baghdad Governorate.

The province is named after Muslim leader Saladin or Salah ad Din, who hailed from the province. The province is also known as the home of Saddam Hussein, who was from the village of Al-Awja.

Saladin Governorate contains a number of important religious and cultural sites. Samarra, the governorate's largest city, is home to both the Al-Askari Shrine (an important religious site in Shia Islam where the 10th and 11th Shia Imams are buried), the Sardab where the 12th Imam al-Mahdi went into occultation, and the Great Mosque of Samarra with its distinctive Malwiya minaret.

Samarra was the capital of the Abbasid Caliphate in the 9th century CE, and today Abbasid Samarra is a UNESCO World Heritage Site.

The ancient Neo-Assyrian Empire Assyrian city of Assur is located in Al-Shirqat District on the banks of the Tigris River. Other sites in the governorate include the Crusader Dome (القبة الصلبية) north of Samarra and the Al-`Ashaq Palace (قصر العاشق).

In January 2014, there were plans announced by Prime Minister Nouri al-Maliki to make the Tuz Khurmatu district into a new governorate due to its Turkmen majority. However, these plans were not implemented.
