**Martin Schechter** (born 1930, Philadelphia) is an American mathematician whose work concerns mathematical analysis (specially partial differential equations and functional analysis and their applications to mathematical physics). He is a professor at the University of California, Irvine.

Schechter did his undergraduate studies at the City University of New York. He obtained his Ph.D. in 1957 from New York University (NYU) with Louis Nirenberg and Lipman Bers as thesis advisors; his dissertation was entitled *On estimating partial differential operator in the L2-norm*. He taught at NYU from 1957 to 1966, and at Yeshiva University from 1966 to 1983, before moving to UC Irvine.

He is the author of the textbook *Principles of Functional Analysis* (Academic Press, 1971; 2nd ed., AMS, 2002).
