A total of eight swimmers (three men and five women) were selected to the South Korean roster for the Games at the end of the qualifying period, with Athens 2004 top eight finalist Nam Yoo-sun and four-time medalist Park Tae-hwan becoming the first to compete at their fourth Olympics. On July 8, 2016, the Korean Olympic Committee officially allowed Park to join the swimming team, following his appeal to the Court of Arbitration for Sport against a three-year suspension imposed by the Committee for testing positive on banned testosterone.
