In a gripping contest between the two Belfast schools, it was Campbell who came out on top via a 24-21 win.
It now means they will face either RBAI or Ballymena Academy in the decider on St Patrick’s Day, with that semi-final taking place on Wednesday.
Campbell have won the competition 24 times, with the last success coming in 2018.
Will they end an eight-year wait next month?
Speaking after the game, College College forwards coach Richard Boyd, said: “Campbell College want to be fighting at finals and semi-finals, that's where we want to be, it still means an awful lot to these guys.”
