The 2020 Open Championship has been cancelled because of the cornavirus pandemic.
The 149th edition of the major was due to start at Royal St George's on July 16.
However, the course in Sandwich will have to wait until 2021 to host the event due to a virus that has killed nearly 5,000 people in the United Kingdom.
St Andrews will be the venue for the 150th Open in 2022.
"I can assure everyone that we have explored every option for playing The Open this year but it is not going to be possible," R&A chief executive Martin Slumbers said.
"Our absolute priority is to protect the health and safety of the fans, players, officials, volunteers and staff involved in The Open. We care deeply about this historic Championship and have made this decision with a heavy heart.
"We appreciate that this will be disappointing for a great many people around the world but we have to act responsibly during this pandemic and it is the right thing to do.
"There are many different considerations that go into organising a major sporting event of this scale. We rely on the support of the emergency services, local authorities and a range of other organisations to stage the Championship and it would be unreasonable to place any additional demands on them when they have far more urgent priorities to deal with.
"In recent weeks we have been working closely with those organisations as well as Royal St George's, St Andrews Links Trust and the other golf bodies to resolve the remaining external factors and have done so as soon as we possibly could. We are grateful to all of them for their assistance and co-operation throughout this process.
"Most of all I would like to thank our fans around the world and all of our partners for their support and understanding.
"At a difficult time like this we have to recognise that sport must stand aside to let people focus on keeping themselves and their families healthy and safe. We are committed to supporting our community in the weeks and months ahead and will do everything in our power to help golf come through this crisis."
The Masters and US PGA Championship were postponed last month but there is said to be hope those events, along with the U.S. Open at Winged Foot, can be contested later in the year.
Shane Lowry, winner at Royal Portrush last year, will hold on to the Claret Jug as a result of the cancellation.
In a post on Twitter, Lowry wrote: "Obviously I'm disappointed that I won't get to defend the Open Championship this year but I feel the R&A have made the right decisions based on people's health and safety. See you all in Royal St George's in 2021."
