Rooney will now be United's new leader taking over from Nemanja Vidic who departed for Inter Milan.
"It is a huge honour for me – and for my family – to be named captain of this great club. It is a role I will perform with great pride," said Rooney.
"Team spirit has always been very high in our dressing room and I am very grateful to the manager for the faith he has shown in me. I look forward to leading the team out on Saturday at our first match of the new season."
Rooney has been in United since 2004 that he joined from Everton,and was no doubt in contention to be named captain with almost all the senior players having left the club.
"For me it's always very important the choice of captain," said United manager Louis Van Gaal.
"Wayne has shown a great attitude towards everything he does. I have been very impressed by his professionalism and his attitude to training and to my philosophy.
"He is a great inspiration to the younger members of the team and I believe he will put his heart and soul into his captaincy role."
"Darren Fletcher will become the vice-captain. Darren is a natural leader and will captain the team when Wayne isn't playing. Darren is a very experienced player and a very popular member of the dressing room, I know he will work well alongside Wayne."
Darren Fletcher on his part said: "I am delighted to have been named as vice-captain. It's a very proud moment for me and my family. Wayne and I have always worked well together and we will continue to work closely together in our new roles. I would like to thank the manager for putting his trust in me."
