The Geelong Falcons product has had a breakout season this year,averaging 32 disposals per game on the back of increased midfield time following injuries to Dylan Shiel and Jye Caldwell.
He has won medals for best afield in games against Collingwood,Richmond and Geelong and is among the favourites for the Brownlow Medal.
“We’re building something pretty special at Essendon and it was a very easy decision to sign on again,” Parish said in a club release.
“We have a really clear plan under ‘Truck’ (senior coach Ben Rutten) and Dyson’s (captain Dyson Heppell) leadership and we’re all really determined and hungry to build on what we’ve started this year,but we know we have a long way to go.
“It’s been a really enjoyable place to be this season. I think that is really evident to our members and supporters and we have a lot of growth in us as a developing team. I’m excited to continue to build my own game and to see what’s in store as we continue to develop as a playing group over the coming years.”
Essendon list chief Adrian Dodoro said he had been rapt with Parish’s development.
”We’re really pleased for Darcy and we’re delighted he will remain with us in the red and black,” Dodoro said.
