Courier won the Davis Cup as a player with the USA in 1992 and 1995
Four-time Grand Slam winner Jim Courier is the new captain of the United States Davis Cup team.
The 40-year-old succeeds Patrick McEnroe, who stepped down in September after 10 years in the role.
Courier said: "I definitely thought that being the captain would be something that I'd enjoy and now I get to see if I will."
His debut as captain will be against Chile in March 2011 as the US aim for a place in the quarter-finals.
As a player, Courier twice won the French Open and Australian Open titles and helped the US win the Davis Cup in 1992 and 1995, finishing with a 16-10 record in singles and 1-0 in doubles.
Known for his big ground strokes and white baseball cap, Courier was number one in the ATP rankings for 58 weeks in 1992-93. After retiring from the professional tour in 2000, he had been working as a TV commentator.
McEnroe, younger brother of tennis legend John, abruptly announced he was stepping down during the US Open, saying he wanted to dedicate more time to his family and other commitments.
Patrick McEnroe had served as United States captain for 10 years, winning the 2007 Davis Cup to end the country's 12-year drought.
He had recommended Courier and former US Open runner-up Todd Martin as possible successors to the US Tennis Association (USTA), who also considered 1996 Wimbledon runner-up Malivai Washington.
If the US win in Chile, they will face either Spain or Belgium in the last eight in July 2011.
"We're certainly going to have a test down there, there's no doubt about that, playing in South America, likely to be on clay," Courier told the USTA website.
In Patrick McEnroe's final tie in September, the US beat hosts Colombia 3-1 to remain in the World Group, the competition's top tier.
Courier added: "There's been a great camaraderie amongst the guys playing for Patrick over the past decade and, if we can keep that same spirit, I think we'll have a great chance to win.
"There's a lot of diversity in the squad. You've got veteran players, with Andy Roddick, Mardy Fish, the Bryans, and hopefully James Blake can get back in the conversation."
The Americans have won the Davis Cup a record 32 times.
