Deane Pappas (born 12 December 1967) is a South African professional golfer. He has won twice on both the Southern Africa-based Sunshine Tour and on the second-tier United States based Buy.com Tour, now the Web.com Tour.

Pappas was born in Phalaborwa. He was a three-time All-American at the University of Arkansas, where he was a teammate of John Daly. He currently lives in Arkansas in the United States with his wife Shona, and two children, Callen and Devyn. They manage Ridgepointe Country Club in Jonesboro.

Pappas turned professional in 1992 and joined the Sunshine Tour in 1994. He won for the first time on the tour in 2001, at the prestigious South African PGA Championship. He claimed his second tour victory in 2009 at the Dimension Data Pro-Am.

Between 1996 and 2007, Pappas played extensively in the United States, winning two tournaments on the Buy.com Tour, the first in 2000 and the second the following year. He has played three seasons on the PGA Tour, the first in 1999 after finishing tied for second place at qualifying school, but has never been able to retain his card.

Pappas's younger brother, Brenden, is also a professional golfer. In 2001, they became the first brothers to graduate simultaneously to the PGA Tour by finishing in the top 15 on the Buy.com Tour money list.
