Muzharul Islam (25 December 1923 – 15 July 2012) was a Bangladeshi architect, urban planner, educator and activist. He is considered as the Grand Master of regional modernism in South Asia. Islam is the pioneer of modern architecture in Bangladesh and the father of Bengali modernism. Islam's style and influence dominated the architectural scene in the country during the 1960s and 70s, along with major US architects he brought to work in Dhaka.

As a teacher, architect, social and political activist, Islam set the course of architectural practice in the country not only through his own many varied works but also through being instrumental in inviting architects like Louis Kahn, Richard Neutra, Stanley Tigerman, Paul Rudolph, Robert Boughey and Konstantinos Doxiadis to work in Bangladesh.
