'''Benjamin Muckenhoupt''' (December 22, 1933, Boston – April 13, 2020, Whippany, New Jersey) was an American mathematician, specializing in analysis. He is known for the introduction of Muckenhoupt weights.<ref>{{cite journal|last = Muckenhoupt | first = Benjamin| title = Weighted norm inequalities for the Hardy maximal function | journal = Transactions of the American Mathematical Society | pages = 207–226| year = 1972 | volume = 165| doi = 10.1090/S0002-9947-1972-0293384-6| doi-access = free}}</ref>

The main focus of Muckenhoupt's mathematical research was harmonic analysis and weighted norm inequalities.<ref>{{cite web|title=Who's That Mathematician? Paul R.

At the State University of New York at Albany he was a visiting professor for the academic year 1970–1971.<ref name=IAS/>

His doctoral students include Eileen Poiani.<ref name=MathGenealogy/>

Upon his death he was survived by his widow, a daughter, a son, and three grandchildren.<ref name=memoriam/>
