The 30-year-old, who is one of his country’s most capped internationals with 84 appearances and was part of the Argentina squad which reached the semi-finals of the 2015 World Cup, will complement Danny Care’s skill-set and provide another level of leadership across the squad.
Landajo will team up with Harlequins from Jaguares following the World Cup in Japan, if selected for the Argentina national squad, and will look to make his debut for the London Club at The Stoop from November 2019.
“I cannot wait to get started with Harlequins,” said Landajo. “I have always admired the Club’s history and place in the English game and, under Paul Gustard, I can see they have become even stronger and are now in a great place to win trophies.”
Paul Gustard, Harlequins Head of Rugby, added: “Martin will be a wonderful addition to the squad and add greater density to our leadership group. They call him The Door Opener – and for good reason. His pace and creativity has been able to unlock defences at the highest level and we look forward to welcoming him at The Stoop later this year.
“He is a very impressive man who is driven to push on, test himself in a different environment and leave his own personal legacy in the game. We are delighted he is committing his future with us and we look forward to welcoming Martin and his young family to Quins.”
