Ibrahim Mushtaq Abdul Razak Nadim Memon, better known by his nickname Tiger Memon, is an Indian gangster and one of the prime suspects in the 1993 Mumbai bomb blasts case. He is wanted by Interpol and the CBI. He is a member of the D-Company gang and is a trusted lieutenant of its leader, Dawood Ibrahim. He got the nickname 'Tiger' after helping a drugs and weapons smuggler to evade the grips of the Crime Branch of Mumbai Police by driving his car dangerously over 100 km/h on one way roads.

His role as the prime accused in the blasts (along with Dawood Ibrahim) has been confirmed by the Special Court after the conviction of the other accused in the case.

On September 12, 2006, the special TADA court, hearing the long-drawn case around the 1993 Bombay bombings, convicted four members of the Memon family - Yakub, Essa, Rubina and Yusuf. Three other members of the Memon family - Suleiman, Hanifa and Rahil - have, however, been acquitted with the judge giving them the benefit of doubt. The four Memons have been held guilty on charges of conspiring and abetting acts of terror. They face jail terms ranging from a minimum of five years to life imprisonment. Yakub Memon, the brother of prime accused 'Tiger' Memon, has been charged for possession of unauthorised arms.
