Two-time AFLW premiership captain Erin Phillips is stepping down from her leadership role at the Crows, with the club focusing on the future.
Phillips skippered Adelaide for the first four seasons alongside Chelsea Randall and together led the team to two flags.
The forward will now turn her attention to fast-tracking the development of the club's emerging leaders.
Crows Head of Women's Football Phil Harper said the move was important for the club's future thinking.
"Erin's decision has been made in conjunction with the club and while we have been discussing it for the last 18 months, we believe this is the right time to make a change," Harper said.
"She has been a fantastic captain over the last four years but this is great chance to take the next step as a group."
Adelaide's 2021 AFLW leadership group will be decided ahead of their upcoming trial match, set to be played on January 17 at Norwood Oval.
