Mustafa Sarıgül (born 1956 in İliç, Erzincan Province, Turkey), is the mayor of the Şişli district in Istanbul, where he was elected as the candidate of Cumhuriyet Halk Partisi for the past two terms.

However, as a member of the CHP he became a known figure of the internal opposition against then party leader Deniz Baykal. It also has been announced that he will not be shown as a candidate for CHP in any other national or local elections again.

It was announced in 2008 that he would officially join the DSP.

In 2009 he formed a new political movement called the Turkish Change Movement (Türkiye Değişim Hareketi) and started work towards forming it into a political party. However, following Kemal Kılıçdaroğlu's succession to CHP's leadership in 2010, he announced that this created an opportunity for change in the CHP, and that he would not form a new party.
