The 30-year-old skippered the Scots in all three of their autumn internationals, and interim coach Scott Johnson has confirmed that he will continue in the Six Nations.
Johnson said: "It was right and proper that the coaches considered captaincy at the same time as we were looking at selection of our squad for the England game.
"We believe Kelly has the qualities we're looking for to captain Scotland.
"Captaincy is about deed in my book, not Churchillian oratory, and the knowledge and experience that Kelly brings to the Test match arena is good for this team. We are also looking at our leadership group and I'll be naming two vice-captains in the team that we announce on Tuesday."
Brown said: "It's a huge honour to captain Scotland. The job now, though, is to work with all the other players in the squad to deliver a performance to make the country proud (against England) this weekend.
"It's a while since I've played against England. I missed out through injury in last year's Six Nations and I was sidelined during the Rugby World Cup match in Auckland as well, so I'm really raring to go."
Meanwhile flanker Alasdair Strokosch has joined up with the squad after being granted time off as his wife gave birth to their second child.
