Guyana were first represented at the Olympic Games the last time they were held in London in 1948 when a four-man team competed as British Guiana.
Since that time, they have competed in five sports: athletics, boxing, cycling, swimming and weightlifting. They first competed under the name Guyana in Mexico City in 1968.
Their only Olympic medal to date is boxer Michael ANTHONY's bantamweight bronze at the Moscow 1980 Olympic Games.
Sprinter Claudette MASDAMMER was the first female Guyanese Olympian when she competed in the 100m and 200m at the Melbourne 1956 Olympic Games.
Weightlifter Martin DIAS was Guyana's lone representative at the Tokyo 1964 Olympic Games, finishing eighth in the bantamweight division.
Gordon CAREW boxed for Guyana in the lightweight division at Los Angeles 1984 and his younger brother Dillon fought as a light welterweight at the Barcelona 1992 Olympic Games.
At the Beijing 2008 Olympic Games, 400m runner Aliann POMPEY competed in his third successive Games.
A Guyana-born athlete took bronze as far back as 1928. Phil EDWARDS was born in Demerera but represented Canada. He collected five bronze medals in an Olympic career that spanned three Olympic Games from 1928 to 1936.
In Melbourne in 1956, Guyana-born Chris BRASHER won the 3,000m steeplechase representing Great Britain.
