Tremayne Dequette Smartt (born 17 September 1985) is a Guyanese cricketer who plays as a right-arm medium bowler and right-handed batter.

[3][4] In 2011, Smartt was suspended for five months after pleading guilty to a doping violation.

Smartt had tested positive to Furosemide, in order to treat a swelling in her knee.

The tribunal accepted that she didn't use the substance for performance enhancing purposes, and Smartt conceded that she did not effectively check the substance's status before use and would accept the consequences as a result.

[5] Smartt returned to the West Indies team shortly after her suspension ended.
