Jung Soo-Keun (Korean: 정수근; Hanja: 鄭守根; born January 20, 1977, in Seoul, South Korea) is a retired South Korean baseball player who played for the Doosan Bears and Lotte Giants of the Korea Baseball Organization.

In February 2003, Jung was arrested in Honolulu, Hawaii, on charges of battery after slashing two men in a Korean restaurant when he was joining the Doosan Bears spring training camp.

On July 26, 2004, Jung was arrested on assault charges for hitting a man with a baseball bat in Haeundae-gu, Busan.

The police was dispatched to the site after receiving a report that he was half-naked, intoxicated and swearing in a karaoke room, but Jung was not arrested.

Because his breathalyzer test revealed a blood alcohol level of 0.12 percent, authorities arrested Jung at the scene for misdemeanor drunk driving.
