The Spaniard, who is currently the world number one, defeated world number two Novak Djokovic in a thrilling final that lasted four sets.
The match began with Djokovic quickly taking the first set 6-1 at the Centre Court.
However, Alcaraz fought back and won the second set with a 7-6 (8-6) tiebreak.
He then went on to win the third set with a comfortable 6-1.
Despite Djokovic's efforts to make a comeback in the fourth set, Alcaraz sealed the final set with a 6-4 win.
With this win, Alcaraz has become the third-youngest men's winner at Wimbledon, after Boris Becker and Bjorn Borg.
In the award ceremony, Alcaraz paid tribute to Djokovic, saying that the Serbian legend had inspired him from a young age.
Djokovic, who has 23 grand slam titles, acknowledged his young opponent's talent and said that he had expected to have more trouble with him on clay or hard courts, but not on grass.
The match was watched by Spain's King Felipe VI, who was present in the Royal Box, and the Prince and Princess of Wales, William and Kate, who brought their children, Prince George and Princess Charlotte, to watch the historic match.
Princess Kate, as the royal patron of the All England Lawn Tennis & Croquet Club, presented the trophy to Alcaraz.
This victory marks a significant milestone in Alcaraz's career and solidifies his position as one of the greatest tennis players of his generation.
