The 29-year-old started his career at Fremantle, playing 69 games after being taken with Pick 11 in the 2011 National Draft.
Then, he made the transition to the Kennel in 2017, where he went on to appear 73 more times at the AFL level.
The rebounding half-back-flanker, who underwent a position change from the forward line to defence during his career, confirmed his retirement via Instagram on Friday.
Crozier battled injury and form inconsistency in the latter stages of his career at the Bulldogs, playing just four senior games this season after a five-game 2022 campaign.
The veteran persevered through knee and shoulder ailments throughout his career, as well as a fainting incident at half-time of a game against Carlton in 2022.
Per the caption of his Instagram post on Friday, Crozier stated he is "so excited for the next phase of my life and what's to come."
