2001–02 UEFA Champions League second group stage

In the second group stage of the 2001–02 UEFA Champions League, eight winners and eight runners-up from the first group stage were drawn into four groups of four teams, each containing two group winners and two runners-up. Teams from the same country or from the same first round group could not be drawn together. The top two teams in each group advanced to the quarter-finals.
