The 2023 Detroit City FC season was the club's fifth professional season since the club was established in 2012, and the team's second season in the USL Championship.
Final 2023 roster
For transfers in, dates listed are when Detroit City FC officially signed the players to the roster. Transactions where only the rights to the players are acquired are not listed. For transfers out, dates listed are when Detroit City FC officially removed the players from its roster, not when they signed with another club. If a player later signed with another club, his new club will be noted, but the date listed here remains the one when he was officially removed from the Detroit City FC roster.
As a USL Championship club, Detroit City FC entered the competition in the second round.
