Todd Demsey (born May 27, 1972) is an American professional golfer on the PGA Tour and 1993 NCAA champion.

He earned All-American honors four years in a row while in college, from 1992 to 1995, and was on the winning American 1993 Walker Cup team.

Back injuries slowed his career on the Nationwide Tour, but the real jolt came in 2002 when he felt constant pressure in his left sinus.

At the end of the year, doctors found a tumor, a fifth nerve schwannoma,[3] behind his left sinus going into his brain.

In 2007, Demsey closed with an 8-under 64 in the sixth and final round of Q-school to earn a full-exempt card for the 2008 PGA Tour season.
