Ireland duo Keith Earls and Denis Leamy have signed IRFU contracts tieing them to Munster until 2014.
Versatile back Earls, who made his international debut in 2008, played for the British & Irish Lions on their tour to South Africa a year later.
"I'm really happy to get my contract completed and am delighted to remain a Munster player," said Earls.
Back-row forward Leamy, who is recovering from surgery on a hip injury, has won 57 Ireland caps.
"I've achieved a lot in my career, winning the Six Nations as well as Heineken and Magners League titles," said Leamy. "But there is always the desire to try to continue that and achieve even more.
"It also makes it more pleasing to do that with Munster and to remain here in Ireland with my home province."
