Clarke has made 17 Twenty20 appearances for Australia
Michael Clarke has been named as Australia's Twenty20 captain.
The 28-year-old succeeds Ricky Ponting, who stood down as skipper in the short form in September to prolong his Test and one-day international career.
"We must recognise that we have got a lot of work to do in Twenty20 cricket and our recent form hasn't been good," said Clarke.
Victoria captain and all-rounder Cameron White has been named as Clarke's vice-captain.
"Cameron White will be an excellent deputy and his recent form has been quite outstanding," added Clarke.
Clarke is Test and one-day vice-captain having succeeded Adam Gilchrist in January 2008, leading Australia in Ponting's absence for three 50-over matches in last month's 6-1 Nat West Series victory over England.
Although Ponting has insisted he wants to continue as Australia captain at the 2011 World Cup, Clarke is seen as the natural heir for both the one-day and Test roles.
"We have developed a strong working relationship and he has always led the team well in my absence," Ponting said of Clarke.
"I am sure he will do a very good job with the Twenty20 team."
