2023–24 Wellington Phoenix FC season

The 2023–24 season is the 17th in the history of Wellington Phoenix Football Club. In addition to the domestic league, the club is participating in the Australia Cup for the ninth time.

Pre-season
On 14 April 2023, it was announced that Ufuk Talay would depart the club at the end of the season. The following week, assistant coach Giancarlo Italiano was announced as the next head coach on a 2-year deal.

On 10 May, the Phoenix announced the departures of eight players, including vice-captain Oliver Sail, Clayton Lewis, Steven Ugarkovic and Callan Elliot.

On 11 May, the Phoenix announced their first signing of the off-season in Mohamed Al-Taay on a two-year deal from the Newcastle Jets. On 18 May, it was announced that Nicholas Pennington had signed a one-year contract extension with the club. On 9 June, the Phoenix announced the signing of Jack Duncan on a one-year deal.

On 27 September, the Phoenix announced their final off-season signing in 17-year old Luke Supyk, who had only joined the club's academy 5 months prior, on a three-year deal. Despite initial criticism, these signings came as a result of the club putting greater emphasis on developing young New Zealand players.
