Pearce, whose previous contract expired at the end of this season, has played 69 career games, including 43 in the past two seasons under Ross Lyon.
General manager of player management Brad Lloyd said Pearce had blossomed into a quality player during the past two years.
“To see his continued development has been a credit to Clancee's commitment to his football and the effort he has put in,” Lloyd said.
“He is an important member of the playing group and we look forward to seeing him continue to play his role for the club in the coming years.”
Pearce played 19 games in 2013 but injured his Achilles in round 23 and missed the finals series.
He had surgery in the off-season and has recently resumed full training, including an appearance in the club’s intra-club match on Tuesday. The 23-year-old has also recently become a father for the first time.
