Roger Federer has been seeded ahead of great rival Rafael Nadal for his 21st appearance at Wimbledon.
Wimbledon is unique among the grand slams in having a formula to calculate seedings giving weight to grass-court performances, and Federer will be the number two seed and Nadal three in a reversal of their world ranking positions.
That means Nadal, who was critical of the system in an interview with Spanish TV on Tuesday, is guaranteed to be in the same half of the draw as either Federer or top seed and defending champion Novak Djokovic.
South Africa's Kevin Anderson is seeded fourth, well ahead of his ranking of eight, after reaching the final for the first time last year, with Dominic Thiem, Alexander Zverev and Stefanos Tsitsipas all bumped down one position.
Kei Nishikori, John Isner and Karen Khachanov round off the top 10 while British number one Kyle Edmund is seeded 30th, one place above his ranking.
The women's seedings are the same as the rankings, with French Open champion Ashleigh Barty top of the pile for the first time at a grand slam ahead of Naomi Osaka.
Defending champion Angelique Kerber is seeded fifth, Serena Williams 11th and British number one Johanna Konta 19th.
Liam Broady is one win away from a fourth appearance in the Wimbledon main draw after winning his second-round qualifying match against Tallon Griekspoor.
Broady, whose ranking has slipped to 287, recovered from losing the second set on a tie-break to come through 6-4 6-7 (2) 6-2 against his Dutch opponent and will face either 12th seed Gregoire Barrere or Brazilian Rogerio Dutra Silva on Thursday.
Broady received wild cards in 2015, when he won his only main-draw match against Marinko Matosevic, 2016 and 2018.
