Bristol sign Australia back Morahan
The 26-year-old has been capped three times and can play at fullback, wing and centre.
Bristol did not disclose the length of his contract.
"Luke is an impressive player with excellent technical abilities," Bristol head coach Mark Tainton told the club website.
"He has got a lot of raw pace and versatility and can play across the backline."
Morahan previously played sevens for Australia, winning a silver medal at the 2010 Commonwealth Games, and has played Super Rugby for Queensland Reds and Western Force.
"I'm excited about the opportunity to play in England, but also to be a part of the ambitious journey that Bristol Rugby is on," Morahan said.
"The club's management sold me the vision and how much rugby means to the people of the city."
Morahan is likely to find himself playing second-tier rugby with Bristol, who are currently seven points adrift at the foot of the Premiership table.
