Glenroy John Gilbert (born August 31, 1967 in Georgetown, Guyana) is a Canadian former track and field athlete, winner of the gold medal in 4×100 metres relay at the 1996 Summer Olympics, and head coach of Athletics Canada.
Born in Guyana, Glenroy Gilbert formed along with Robert Esmie, Bruny Surin and Donovan Bailey the best 4 × 100 m relay team in the mid-1990s.
He was a member of the Louisiana State University track and field team.
Gilbert made his major international championships debut at the 1988 Summer Olympics, where he was 21st in the Long Jump. At the 1990 Commonwealth Games, Gilbert was eighth in long jump, and reached the semifinal as a member of Canada's 4 × 100 m relay team at the 1992 Summer Olympics.
Gilbert won his first medal at the 1993 World Championships, when the Canadian 4 × 100 m relay team finished in third place. At the 1994 Commonwealth Games, Gilbert won the gold medal in 4 × 100 m relay and was fifth in 100 m. Gilbert also competed in bobsleigh at 1994 Winter Olympics, where he finished fifteenth in two-man bobsled and eleventh in four-man bobsled.
In 1995, Gilbert won a gold medal in 100 m at the Pan-American Games and was a member of gold medal winning Canadian 4 × 100 m relay team at the 1995 World Championships.
At the Atlanta Olympics, the Canadian relay team weren't the favourites, although they won almost all the titles available during the last couple of years. At the 4 × 100 m relay final, the Canadian team beat United States by almost half a second, to establish itself the best relay team in the world. Gilbert also reached the quarterfinals of the 100 m.
Gilbert and the Canadian team won a gold medal again at the 1997 World Championships and at the 1998 Goodwill Games, but again in absence of United States. At the 1999 World Championships the Canadian team were disqualified in semifinal and Gilbert ended his running career after the 2000 Summer Olympics, where the Canadians were eliminated in the semifinal.
After his retirement, Gilbert worked for a short time in CBC radio in Ottawa. He became coach for the Ottawa Lions Track & Field club, coaching sprints and relays. He has worked with Athletics Canada since 2006, primarily as coach of the Canadian men's and women's relay teams.
In July 2017 he was named Athletics Canada's permanent head coach; he had earlier been named head coach for the August 2017 world track and field championships.
In 2008 he was inducted into Canada's Sports Hall of Fame as part of the 1996 Summer Olympics 4x100 relay team.
