Grenada at the 2000 Summer Olympics

Grenada competed at the 2000 Summer Olympics in Sydney, Australia, which were held from 15 September to 1 October 2000. The country's participation in Sydney marked its fifth appearance at the Summer Olympics since its debut in 1984. The athlete delegation of the nation consisted of three athletes: sprinters Rudy Sylvan and Hazel-Ann Regis, who would be designated as the flag bearer for Grenada, and swimmer Omar Hughes.

Hughes would first compete for the nation, competing in the men's 50 metre freestyle. There, he would place fifth in his heat and would not advance further. Sylvan and Regis would compete in the same day, competing in the heats of the men's 400 metres and women's 400 metres, respectively. Both of them would place seventh in their heats, not advancing further.
