The 2023–24 season was the 140th season in the history of Derby County and their second consecutive season in League One. In addition to the league, the club also competed in the FA Cup, the EFL Cup and the EFL Trophy.
After a slow start to the season which saw the pre-season promotion favourites eight points off of the promotion places with a third of the season gone, Derby's form improved and a mid-season run of 14 wins from 19 games between late-October and mid-February took them into second place and the automatic promotion spots, a position they would not relinquish. A 2–0 home win over already-relegated Carlisle United on the final day of the season confirmed the club's first automatic promotion in 28 years and saw them return to the Football League Championship at the second attempt.[1][2]
Along the way, the team set club records for points in a season (92, eclipsing the 85 achieved in 2013–14) and most away wins (13, eclipising the twelve away wins in 2004-05 and 2006-07), and equalled the club record for most wins in a single league campaign (28, matching that of the 1955–56 season).
