The Duke and Duchess of Cambridge will be joined by Prime Minister David Cameron, Scotland First Minister Nicola Sturgeon and Hollywood stars Benedict Cumberbatch and Bradley Cooper in the Royal Box as Andy Murray aims for a second Wimbledon title.
The Duchess was a guest at the All England Club earlier in the week when she revealed that Prince George already has a tennis racket and has taken a shine to the sport.
It will be William's first visit of this year, and the couple will be hoping Murray can land his third grand slam title.

Serena Williams returned to Centre Court to win her second Wimbledon title of the day as she and sister Venus triumphed in the doubles final.
Their sixth Wimbledon success as a team came at the expense of Yaroslava Shvedova and Timea Babos, with the Williams pairing earning a 6-3 6-4 victory.
Between beating Angelique Kerber in straight sets to take the singles title and being called to the court for the doubles, Serena Williams had paraded her trophy, signed autographs, held a press conference and conducted television interviews.
But the 34-year-old and her 36-year-old sister showed little sign of distraction as they were comfortable winners against Kazakh player Shvedova and Hungarian Babos, Serena Williams putting away the match-winning backhand volley at the net.
Nicolas Mahut earned a new place in the Wimbledon history books as he and Pierre-Hugues Herbert won the men's doubles title in an all-French final.
The 34-year-old Mahut is best known to many as the player who lost the longest tennis match of all-time, the 11 hours and five minutes clash on Wimbledon's Court 18 in 2010 that John Isner won after a 70-68 final set.
This time it was a Centre Court victory for Mahut to savour as he and Herbert justified their top seeding by beating unseeded Julien Benneteau and Edouard Roger-Vasselin 6-4 7-6 (7/1) 6-3.
Victory secured the winners £350,000 to split between themselves, and a second grand slam title following their victory at the US Open last September.
Heather Watson became Britain's latest Wimbledon finalist alongside Finn Henri Kontinen in the mixed doubles.
The pair, who had never played a match together prior to this tournament, defeated Oliver Marach of Austria and Latvia's Jelena Ostapenko 7-6 (7/1) 6-3 in the semi-finals on Court One.
Watson will now hope to make it a British double when she and Kontinen follow Andy Murray onto Centre Court on Sunday to take on Colombia's Robert Farah and Anna-Lena Groenefeld of Germany.

Great Britain's Alfie Hewett and Gordon Reid won the Wimbledon wheelchair men's doubles title in a dramatic match that went to a final-set tiebreak.
The home favourites and second seeds got the better of French players Stephane Houdet and Nicolas Peifer, winning 4-6 6-1 7-6 (8/6) on Court 17.
The coach who set Milos Raonic on the road to the Wimbledon final has no doubt his former pupil will prove too strong for Andy Murray on Sunday.
It was a day just like any other in early 1999 when father Dusan, heeding the advice of his barber, took the eight-year-old Milos along to the Blackmore Tennis Club in Richmond Hill, Ontario, on the Toronto outskirts.
Located in a well-to-do neighbourhood, the club and its coach Casey Curtis had established a reputation for nurturing talent, and Dusan was willing to indulge his young son's wide-eyed enthusiasm for the sport.
The moment Curtis set eyes on Raonic that day was one of epiphany.
"Believe it or not, on the first day I turned to my assistant and said, 'I think that kid's going to be number one in the world one day'," Curtis said.
"The balls were flying all over the place but the boy could really swing a racket, and that's a huge asset. He had a tremendous passion for the game and he listened really well and learned very well.
"I actually believe that if there's one guy in the top five that Milos thinks he can handle, it's Andy. I think he beats Andy on Sunday."
