Edriss Saleh Titi (born March 22, 1957; Arabic: إدريس صالح تيتي) is an Arab-Israeli mathematician. He serves as a professor in Computer Science and Applied Mathematics at the Weizmann Institute of Science and at the University of California, Irvine.

Titi was born into an Arab family in the Old City of Acre. He attended the private Terra Santa School in the city and excelled in mathematics and physics.
In 1974, he began his studies at the Technion – Israel Institute of Technology, where he earned a B.Sc. in Mathematics in 1979. In 1981, he received an M.Sc. in Theoretical Mathematics from the same institution under the supervision of Prof. Dov Aharonov.
In 1986, he completed his Ph.D. at Indiana University, after which he conducted postdoctoral research at the University of Chicago. He then served as a lecturer at Cornell University for two years before joining the University of California, Irvine, where he was promoted to Full Professor in 1989.
In 1999, he began serving as a Visiting Professor at the Weizmann Institute of Science, and in 2003, he joined the Institute’s Department of Computer Science and Applied Mathematics.

Titi’s research focuses on the development of analytical and computational methods for studying nonlinear systems. In particular, his work deals with the Navier–Stokes equations and related differential equations, as well as their application to a variety of engineering and physical models.
