Sidi Gaber is a neighbourhood in Alexandria, Egypt.

Khaled Mohamed Saeed was an Egyptian man whose death in police custody in the Sidi Gaber area of Alexandria on 6 June 2010 helped incite the Egyptian Revolution of 2011. Photos of his disfigured corpse spread throughout online communities and incited outrage over the fact that he was beaten to death by Egyptian security forces. A prominent Facebook group, "We are all Khaled Said", moderated by Wael Ghonim, brought attention to his death and contributed to growing discontent in the weeks leading up to the Egyptian Revolution of 2011. In October 2011, two Egyptian police officers were found guilty of manslaughter and sentenced to seven years in prison for beating Saeed to death. They were granted a retrial and sentenced to ten years in prison on 3 March 2014.
