Mustafa Reşid Pasha, Ottoman politician, 212th Grand Vizier of the Ottoman Empire (d. 1858)
Koca Mustafa Reşid Pasha (literally Mustafa Reşid Pasha the Great; 13 March 1800 – 7 January 1858) was an Ottoman statesman and diplomat, known best as the chief architect behind the Ottoman government reforms known as Tanzimat.

Born in Constantinople (now Istanbul) in 1800, Mustafa Reşid entered public service at an early age and rose rapidly, becoming ambassador to France (1834) and to the United Kingdom (1836), minister for foreign affairs (1837), and once again ambassador to the United Kingdom (1838) and to France (1841). In the settlement of the Oriental Crisis of 1840, and during the Crimean War and the ensuing peace negotiations, he rendered important diplomatic services to the Ottoman state. He returned a third time as ambassador to France in 1843. Between 1845 and 1857, he held the office of Grand Vizier six times.

One of the greatest and most versatile statesmen of his time, thoroughly acquainted with European politics and well-versed in national and international affairs, he was a convinced partisan for reform and the principal author of the legislative remodeling of the Ottoman administration known as Tanzimat. His efforts to promote reforms within the government led to the advancement of the careers of many other reformers, such as Fuad Pasha and Mehmed Emin Âli Pasha.
