He was born on Tuesday (NZT), making him two days old when he was revealed to the world.
Photos posted to the Duke and Duchess of Sussex's Instagram account show the proud parents introducing him to Queen Elizabeth and her husband Prince Philip.
"This afternoon Their Royal Highnesses introduced Her Majesty The Queen to her eighth great-grandchild at Windsor Castle," they wrote on Instagram. "The Duke of Edinburgh and The Duchess' mother were also present for this special occasion."
Two days is relatively late for a royal baby to face the cameras, as mothers have typically appeared on the steps of the Lindo Wing at St Mary's hospital hours after announcing the birth.
The Duke and Duchess announced in the late stages of Meghan's pregnancy they would not be taking part in the tradition, skipping St Mary's entirely. Instead, they would take some time to get to know the child before letting the world meet him.
Archie is seventh in line to the throne, following the Prince of Wales, the Duke of Cambridge and his children, and then Prince Harry.
