Omar Bienvenido Borrás Granda (born 15 June 1929) is a former Uruguayan football coach.
He was the coach of the Uruguay national football team at the 1986 FIFA World Cup. During that tournament, he was banned from the sidelines for their second round match against Argentina due to Uruguay's rough play for their previous game against Scotland, and also his remarks towards the referee after the match.
It is also believed that he was the first person to use the term the "Group of Death", to describe their first round group with West Germany, Denmark and Scotland.
