Zakir Naik (born 18 October 1965 in Mumbai, India) is an Indian Islamic preacher, who has been called an "authority on comparative religion", "perhaps the most influential Salafi ideologue in India", and "the world's leading Salafi evangelist". He is the founder and president of the Islamic Research Foundation (IRF), and founder of the "comparative religion" Peace TV channel, through which he reaches a reported 100 million viewers. Unlike many Islamic preachers, his lectures are colloquial, given in English not Urdu or Arabic, and he wears a suit and tie rather than traditional garb.

Before becoming a public speaker, he trained as a medical doctor. He has published booklet versions of lectures on Islam and comparative religion. Although he has publicly disclaimed sectarianism in Islam, he is regarded by some as an exponent of the Salafi ideology, and, by some, as a radical Islamic televangelist propagating Wahhabism.
