Mir Noor-ud-din Mengal (Urdu: میر نورالدین مینگل; 13 July 1952 – 13 October 2010) was a prominent Baloch Pakistani politician who played a significant role in Balochistan's political landscape for nearly four decades, from 1970 to 2010.

A member of the Zagar Mengal tribe, he was the nephew of the Baloch national poet Mir Gul Khan Nasir. His father, Mir Lal Bakhsh Mengal, and his mother, a member of the Gichki family from Makran, raised him alongside his seven siblings.

Mir Noor-ud-din was named after Sardar Noordin Mengal (an uncle of Sardar Attaullah Mengal and a close friend of Mir Lal Baksh Mengal who died in a road traffic accident near Kalat). He was brought up in his hometown of Kalat. His father was a prominent tribal and political figure of Balochistan while his uncle Gul Khan Nasir belonged to the top tier Baloch leadership along with Ghaus Bakhsh Bizenjo, Abdul Aziz Kurd and, later, Sardar Ataullah Khan Mengal and Khair Bux Marri. As a result of this he was exposed to politics from a very early age. This exposure instilled a nascent sense of political awareness in him which, with age, kept growing.

Mengal passed high school from Kalat and after matriculating from Noshki, enrolled in F.Sc Pre-Engineering in Government Science College, Quetta.

After he had finished college, Gul Khan Nasir advised Mengal to get into a university instead of just relying on a college degree. Following his uncle's advice, he applied to Patrice Lumumba University and was accepted. Mengal had chosen a University in Moscow because at that time it was a very common practice for Baloch students to go to Russia in pursuit of a higher education but because of his political activities (which he had already begun by 1970 from Baloch Students Organization's (BSO) platform) his name was put on the Exit Control List and he was unable to go.

With that door closed, Mengal applied for Mining Engineering at University of Engineering and Technology, Lahore in 1973 and was, once again, accepted. He spent four years in Lahore and graduated with a B.E Degree in 1977.

Throughout his student life, Mengal had been active in politics and from 1974 to 1976 had served as BSO's Vice Chairman. During his time in Lahore he had opened sixteen units of BSO in different cities of Punjab. After returning to Quetta he served a second term as the Vice Chairman of BSO from 1978 to 1980 and while he managed to secure a job as a Mining Engineer in a private mining company, his political life remained dominant over his professional life. So much so, in fact, that he eventually quit his job to devote all his time and energy to politics.

After serving his second term as the Vice Chairman of BSO, he joined the political party of Ghaus Bakhsh Bizenjo, The Pakistan National Party. After Mir Ghaus Bakhsh's death in August 1989, the leadership of the party shifted to Mir Bizen Bizenjo but he wasn't able to hold on to it for long. When Mir Bizen vacated the office of the Party President, PNP was thrown into turmoil. During this tumultuous time the position of Party Organizer was also vacant, so Mir Noor-ud-din Mengal was named the Organizer of the Party. After successfully organizing the council session of PNP where Mir Hasil Bizenjo was named president, Mengal went back to being the Deputy Organizer of the Party while Raziq Bugti became the Organizer. A few months after this, in 1992, Mir Noor-ud-din was elected as the Vice President of PNP, an office he held until the merger of PNP with BNM in 1996.
