Ireland and Leinster prop Marty Moore has agreed to join Wasps ahead of the 2016/17 season.
Moore made his international debut in 2014 and has since gone on to win 10 caps for his adopted Ireland having been part of Ireland's last two RBS 6 Nations title-winning squads.
The 24-year-old Australian-born tighthead has made 58 appearances for Leinster since making his professional debut for the province back in 2012.
"Marty has already proven his international pedigree with Ireland and, at only 24, he has plenty of years ahead of him to continue his development and become a top-class tighthead," Wasps director of rugby Dai Young told the official club website.
"We already have talented tightheads at the club, but his addition will strengthen the depth we have in this key position and will help to drive competition for places, which is what we are trying to achieve throughout the squad."
Wasps have not disclosed the length of Moore's deal at the Ricoh Arena.
Moore has been named as part of Ireland's 35-man squad for their first two Six Nations games against Wales and France but limped out of Leinster's European Champions Cup defeat to Wasps last weekend with a hamstring injury.
"I'm really pleased to have signed a contract with Wasps to join next season," Moore said.
"I am looking forward to working with Dai Young and his coaching team as well as the squad and am excited about the challenge ahead in the Aviva Premiership."
