The 2023 VAFA season was the 122nd season of the Victorian Amateur Football Association (VAFA), the largest senior community Australian rules football competition in Victoria. The season began on 15 April and concluded on 15 September, with 63 teams participating across seven divisions under a promotion and relegation system.
Accounting firm William Buck signed a three-year sponsorship deal extension with the VAFA on 24 April 2023, which included continuing the naming rights for the "William Buck Premier Division", continuing a partnership that began in the 2010s.
The VAFA signed a three-year agreement with KommunityTV, News Corp Australia's live-streaming platform, which saw the platform exclusively broadcast 48 matches throughout 2024. KommunityTV had broadcast 2022 finals matches as part of a trial arrangement.
Following the conclusion of the 2022 season, Manningham Cobras merged with Yarra Old Grammarians in order to keep both clubs viable on and off-field. On 19 September 2022, the formation of Old Yarra Cobras Football Club was announced.
In November 2022, the VAFA revealed Westbourne Grammarians Football Club would not field senior teams in 2023 (having meant to be relegated from Division 3) to Division 4), and would instead field a team in the Thirds competition. However, Westbourne announced on 31 March â around two weeks before the start of the season â that they would not field the thirds team, instead using 2023 to "regroup" as a club.
On 23 February 2023, Premier C club Old Mentonians announced that they would go into recess and not field any teams in 2023 because of a player shortage.
Prahran/Assumption members voted on 30 November 2022 to revert to the club's traditional name of Prahran Football Club, which was reflected in the 2023 season.
Additionally, Emmaus St Leo's renamed to Wattle Park Amateurs Football Club due to "extenuating circumstances".
Collegians won their 18th Premier Division premiership, defeating St Kevin's by 85 points.
St Bernard's won their 5th Premier B premiership, defeating by 31 points in the grand final to complete a perfect season. Fitzroy was promoted to the highest grade the first time since the club entered the VAFA.
Beaumaris were found to have fielded an ineligible player in their round 11 loss to St Bedes/Mentone Tigers and round 12 victory over St Bernard's. On 18 July, the VAFA announced Beaumaris would lose the four premiership points that was gained in their victory, along with their "points for" score from both games. Beaumaris appealed the decision, but it was upheld on 3 August.
As a result of gaining the four points that Beaumaris had lost, St Bernard's finished with a perfect season.
