James Dun joins Quins

Harlequins are delighted to confirm the signing of second row James Dun ahead of the 2026/27 season.

Dun (26) hails from the South West and arrives at The Stoop from Bristol Bears, where he has progressed through the Bears’ pathway to represent the First Team on 57 occasions to date.

The 126kg lock possesses a tireless work rate in the loose and will add further firepower to the Harlequins pack in both the scrum and lineout.

The former England Under-20 international gained valuable experience early in his career through loan spells, including a standout season with Jersey Reds, where he played a key role in the islanders’ 2022/23 Championship title-winning campaign.

Following his return to the Gallagher PREM, Dun enjoyed an impressive breakthrough season in 2023/24, establishing himself as a consistent performer for the West Countrymen.

“Joining Harlequins is an exciting step in my career. It’s a Club that I’ve always had a lot of respect for, with an exciting brand of rugby that I can’t wait to be part of,” said Dun.

“The Club has such a strong sense of identity, a brilliant culture, and a great connection with its fans. I’m really looking forward to being part of the environment, learning from the people within it and contributing in the best way I can on and off the pitch.

“It’s an exciting new chapter and I can’t wait to experience what it means to be part of the Quins family at The Stoop.”

Senior Coach, Jason Gilmore added: “James is a quality tighthead lock who really prides himself on his set piece and his work in the collision area.

“He’s a great young man with a strong attitude and a real desire to keep improving every day. That drive to be the best he can be is exactly what we want in our environment. 

“He’ll add real presence, quality, and further size to our pack, and we’re excited to see the impact he’ll have within the group.”
