The mother of Christopher Moltisanti. She was married to Dickie Motisanti, who was Carmela Sopranos first cousin.
Joanne did not seem to be very motherly to Christopher. She was annoyed with him about his drug habit, although she herself was a heavy wine drinker. When Christopher found an old picture of his father in a US Navy uniform when he was a young man, he figured his mother would be touched by this. Chris went to his mother, saying that there were not many pictures of Dickie Moltisanti, she dismissed the gensture and instead derided Christopher about how life is passing him by.
