James Albert Sethian is a professor of mathematics at the University of California, Berkeley who works in applied mathematics.

Sethian invented the level set method in 1988 together with Stanley Osher. Sethian popularized the fast marching method, invented by John N. Tsitsiklis, an MIT Professor, for solving level set problems.

Sethian received the Norbert Wiener Prize in Applied Mathematics in 2004. This prize is awarded "for an outstanding contribution to applied mathematics in the highest and broadest sense." Sethian was honored "for his seminal work on the computer representation of the motion of curves, surfaces, interfaces, and wave fronts, and for his brilliant applications of mathematical and computational ideas to problems in science and engineering."
