Great Britain's four-time Olympic gold medallist has been confirmed as an entrant as he looks to win the race for the first time.
Farah finished third in this year's event in London but has since won his first major marathon title by claiming victory in Chicago in a European record time.
And the 35-year-old, who has previously declared his intention to target the marathon at the Tokyo Olympics in 2020, is hoping to continue his progress on the streets of the capital on Sunday, April 28.
“I'm delighted to confirm I'll be returning to race the Virgin Money London Marathon again next year,” he said.
“I've often said how racing in London is very special to me and the London Marathon gives me the chance to run in front of my fans, on my home roads, where the atmosphere is like nothing else.
“I feel I have made great strides in the past year, finishing third in London in April and winning my first major marathon in Chicago in October.
“That and breaking both the British and European records has given me the confidence that I can compete against the best marathon runners in the world.
“London always puts together a world-class field and I expect that will be exactly the same in 2019 and I can't wait for the challenge.”
