ParalympicsGB has named UK Sport chief operating officer Tim Hollingsworth as its new chief executive.
Hollingsworth, 44, takes over from Phil Lane, who stepped down in February after 10 years in charge.
He will join the association in July, ahead of its 2012 simulation camp in Bath in August.
"I am thrilled to join the association at this vital time in its history ahead of London 2012," Hollingsworth said.
"There is a tremendous opportunity not just to maximise our athletes' success at the Games but also to drive a step-change in Paralympic sport and its ability to impact on attitudes and change people's lives.
"I look forward to playing my part with a great team to deliver this."
Great Britain finished second in the medal table at both the 2004 Athens Paralympics and the Beijing Games four years later.
ParalympicsGB chairman Tim Reddish added: "This is a crucial appointment for our organisation as we head into what will be the most important Games ever for Paralympic sport in the UK.
"Tim stood out from a field of high calibre candidates and impressed us with his track record of building relationships in both the sporting and commercial sector.
"This, coupled with his clear passion for Paralympic sport and in-depth knowledge of the challenges and opportunities presented by a home Games, mean that we believe he is the ideal candidate to lead the organisation through 2012 and beyond."
