The 70-year-old has signed a two-and-a-half year contract after moving to the club from Motherwell along with his assistant Archie Knox.
Aberdeen chairman Stewart Milne told his club’s official website: “I don’t think it’s any secret Craig and Archie were our first choice and it’s fantastic that they’ve agreed to come on board
“It was important to confirm the new team as quickly as possible while at the same time ensuring we secured the correct people and it’s only thanks to a great deal of hard work and determination over the course of this week that we’ve managed to conclude things so quickly.
“In particular, I would like to thank Duncan and Willie for their efforts this week in assisting me to persuade Craig and Archie their futures lay at Pittodrie.
“Neil Cooper and Neil Simpson, who have done an excellent job in the interim, will be in the dugout for tomorrow’s match at Tynecastle with Craig and Archie being introduced to the media on Monday morning prior to taking their first training session.”
