Nigmatilla Tulkinovich Yuldashev (Uzbek: Ниғматилла Тўлқинович Йўлдошев, romanized: Nigʻmatilla Toʻlqinovich Yoʻldoshev; born 5 November 1962)[1] is an Uzbek lawyer and politician who served as Chairman of the Senate of Uzbekistan from 2015 until 2019.

After graduating from the law department of Tashkent State University in 1985, Yuldashev joined the city prosecutor's office in Olmaliq.

In 2006 he was appointed as head of the Department of Tax and Money Laundering at the General Prosecutor's Office, and in 2008 he became Deputy Prosecutor General.

[1] On 21 July 2011 he was appointed Minister of Justice as a result of presidential decree УП-4323.

However, there was no official confirmation that he had taken up the post and after a few days he proposed that Prime Minister Shavkat Mirziyoyev (seen by observers as Karimov's likely successor) take the post instead, in light of the latter's "many years of experience", and Mirziyoyev was accordingly appointed as interim President by a joint session of both houses of parliament on 8 September 2016.
