Jack Dellal (2 October 1923 – 28 October 2012) was a British property investor. Nicknamed "Black Jack". His company, the property group Allied Commercial Holdings, financed the purchase of Shell Mex House in 2002 and sold it in 2007. Dellal had a net worth of £6.5 billion. 
Dellal was born in Chorlton-cum-Hardy, Manchester, to immigrant Iraqi Jews Sulman Dellal and Charlotte Shashoua. He was educated at Heaton Moor College, also in Manchester. Dellal worked with his father from the early age of 18 selling cloth. He later then retired at the age of 23.
Dellal was a banker in the 1970s. He owned the Dalton Barton bank, which he sold to Keyser Ullman for £58 million. He set up Allied Commercial in 1974 with Stanley Van Gelder, with whom he worked for over forty years. One of their deals was the flip of central London's Bush House, which made £750 million within two years. He was said to have invested up to £200m in London's Dolphin Square.
Through two marriages and at least one long term relationship, he had nine children, seven daughters and two sons.
