Alaa Mubarak (Arabic: علاء مبارك), or Alā'-ud-dīn Muhammad Husni Sayyid Mubarak (Arabic: علاء الدين محمد حسنى سيد مبارك) (born 1961) is an Egyptian businessman and the elder of two sons of ousted president Hosni Mubarak of Egypt, who served from 1981–2011, and his wife Suzanne Mubarak.
He keeps a much lower profile than his younger brother, Gamal, and is not involved in politics. Within the family, under his half-British mother, his name is 'Alan', while his brother is 'Jimmy'.
Alaa attended St. George's College, Cairo for his early education; then he graduated from the American University in Cairo. He is married to Heidy Rasekh, and the couple have two sons: Muhammad and Omar. Muhammad died on 18 May 2009, aged 12, after suffering a 'severe health crisis' (a brain haemorrhage).
Just before his father's resignation Alaa had a bitter argument with his brother Gamal Mubarak. He reportedly told him "Instead of working to help your father be honoured at the end of his life, you helped damage his image this way," The two brothers almost came to blows and senior palace officials had to interfere in order to cool down both men.
On 13 April 2011, Alaa was imprisoned for 15 days pending investigations for corruption, abuse of power, and for his alleged role in causing the fatalities and casualties of peaceful protesters during the Revolution.
