The Hennessy Round-robin Tournament was a 12-man round-robin golf tournament on the British PGA circuit contested in 1964. It was one of two round-robin events during the season, the Esso Golden Tournament being the other.
In essence, the Hennessy Round-robin was merely a change in format for the Hennessy Tournament, a 72-hole stroke play tournament which ran from 1957 to 1965. It was played at the Clandeboye Golf Club near Bangor, County Down, Northern Ireland, which had been the venue for the Hennessy Tournament since 1962. Total prize money was £1,500.
The tournament involved teams of three from each of the home nations, with every player completing eleven 18-hole matches with points awarded for matches won or halved. Harry Weetman won the individual event and alongside Peter Alliss and Bernard Hunt, his England team won the team prize.
