Jon Francis Koncak (born May 17, 1963) is an American former professional basketball player. A 7'0" center from Southern Methodist University (SMU), Koncak was selected with the fifth pick in the 1985 NBA draft by the Atlanta Hawks. Koncak spent ten seasons with the Hawks (1985–1995), mainly in a reserve role, then concluded his career with the Orlando Magic. He retired in 1996 with career totals of 3,520 points and 3,856 rebounds.

Koncak received a six-year, $13 million contract from the Hawks in 1989 – an unprecedented total for a reserve. Since he was a restricted free agent at the time, the Atlanta Hawks matched this offer from the Detroit Pistons. As a result, he earned the derisive nickname "Jon Contract".[1][2]

On February 23, 2008 SMU retired Koncak's jersey.[3] Koncak is an Eagle Scout.[2]

Koncak also won a gold medal at the 1984 Summer Olympics as a part of the United States men's basketball team.
