Bryan Tay (born Tay Zhi Rong, born 13 April 1988) is a Singaporean swimmer, who specialized in individual and relay freestyle events. He is also a multiple-time medalist for the individual events, and a two-time defending champion for the relay freestyle events at the Southeast Asian Games.
Tay was the sole male swimmer for the Singapore national team at the 2008 Summer Olympics in Beijing, and competed for the men's 200 m freestyle. He won the second heat of the competition, and set a national record, with a time of 1:50.41, 0.86 seconds ahead of Estonia's Vladimir Sidorkin. Tay, however, failed to advance into the semi-final rounds, as he placed forty-first in the overall rankings.
Tay was also a member and varsity player of the Princeton Tigers swimming team at Princeton University.
