Supporters from both clubs had already started to arrive at the Turk Telekom Arena ahead of the derby, prior to the announcement by the Turkish footballing authorities.
Sunday's Istanbul derby between Galatasaray and Fenerbahce has been postponed amid security fears following the bombing of a popular shopping street in Istanbul on Saturday.
The announcement from the Turkish footballing authorities has come just 65 minutes before the match was due to kick at the Turk Telekom Arena, with fans already congregating.
It was originally reported that the eagerly-anticipated clash was set to take place behind closed doors, before it was decided that the game was to be called off completely.
