The 2021 Carlton Football Club season was the Carlton Football Club's 158th season of competition.

It was the club's men's team's 125th season as a member of the Australian Football League. The team finished 13th out of eighteen teams with an 8–14 record in the 2021 AFL season – two positions lower than in the 2020 season, ultimately resulting in the sacking of coach David Teague at the end of the season.

It was the club's women's team's fifth season as a member of the AFL Women's competition. The team narrowly missed the finals for the 2021 AFL Women's season, finishing 7th with a record of 5–4.

Individually, Carlton players won the leading goalkicker awards in both the men's and women's senior competitions: Harry McKay winning the Coleman Medal with 58 goals, and Darcy Vescio winning their second leading goalkicker award with 16 goals.

The club also fielded its men's reserves team in the Victorian Football League for the first time since 2002, and fielded a women's team in the VFL Women's competition.

Club summary The 2021 AFL season will be the 125th season of the VFL/AFL competition since its inception in 1897; and, having competed in every season, it will also be the 125th season contested by the Carlton Football Club.

Contractually, Carlton's primary home ground will continue to be the Melbourne Cricket Ground, with many games also to have been played at Marvel Stadium, and traditional home ground Ikon Park to serve as the training and administrative base. The club fielded its women's team in the fifth season of the AFL Women's competition, and Ikon Park served as the home ground for AFL Women's matches. Restrictions associated with the ongoing COVID-19 pandemic meant that crowds were often restricted to well short of the grounds' maximum capacities.

Carlton terminated its alignment with the Northern Blues in the Victorian Football League in March 2020 as a cost-saving measure during the coronavirus pandemic; and will re-establish its reserves team for the first time since 2002, which will contest its fourth overall season in the VFL.

Car manufacturer Hyundai, which had been a major sponsor of the club continuously since 2008, continued its partnership with the club through the season. Airline Virgin Australia, which had upgraded from a secondary sponsor to a major sponsor during the 2017 season, but was struggling owing to the Covid-19 pandemic, continued as the second major sponsor until mid-season; they were then replaced as major sponsor by Great Southern Bank (just recently rebranded from Credit Union Australia), who took on the major co-partner role in a three-year deal.

For the fourth consecutive season, the club set a new membership record, surpassing the 2020 total of 67,035 members on 1 February, and finishing with 81,302 members. The club became debt-free for the first time since financing the construction of Ikon Park's Legends' Stand in 1996, having cleared $7 million in debt since 2017, despite the impact of the COVID-19 pandemic. The club also ceased to accept financial assistance from the AFL.

Impact of the COVID-19 pandemic The season was played during the second year of the COVID-19 pandemic. As the season began, Australia had largely settled into a paradigm of most states maintaining zero COVID-19 cases outside of their international travel quarantine systems; this allowed football games to be played in front of crowds, usually with reduced capacity, and unhindered interstate travel was permitted without quarantine. However, the different state governments often responded quickly to small numbers or even single virus cases being discovered in the community; this meant border restrictions or quarantine periods were at times re-introduced at short notice, impacting interstate travel for games; and, in some cases, that city- or state-wide lockdowns could be imposed within the impacted states, precluding football activities altogether.

Direct, short notice impact to Carlton's senior seasons as a result of the pandemic were: During the Victorian 13–17 February snap lockdown, the women's team's Round 3 match was closed to spectators at one day's notice; During the Victorian snap lockdown which began on 28 May, the men's team's departed Victoria three days ahead of its normal schedule for its Round 11 match against in Sydney; the team then remained in Sydney for the following week and played its Round 12 home game there at the neutral Sydney Cricket Ground against instead of at the Melbourne Cricket Ground. As a result of Perth becoming a hot zone in late June, the men's team's away game against was played at the Melbourne Cricket Ground. Lockdowns and ongoing restrictions in Victoria saw men's matches from Round 18 onwards closed to spectators.

Senior personnel Mark Lo Giudice continued in his final season as club president, a role he had held for a total of almost eight years since mid-2014. Lo Giudice's replacement, club director and former PriceWaterhouseCoopers CEO Luke Sayers, was announced in April with the pair to prepare for the transition during the year. As part of the transition, and in response to the club's weaker than expected start to the season, Lo Giudice commissioned a review of the club's football department, which was conducted by Sayers, CEO Cain Liddle, and external panel members Matthew Pavlich, Geoff Walsh and Graham Lowe, from which followed substantial changes to the club's administration and football department in 2021. Sayers officially took over on August 17, 2021, one round before the end of the season.

David Teague continued in his second full season as appointed senior coach, having also served a half-season as caretaker in 2019. The coaching panel was reduced in size as a result of seeking cost savings and meeting the AFL's soft spending cap due to the coronavirus pandemic, which saw head of coaching performance Henry Playfair, former Northern Blues senior head coach Josh Fraser, development coach Jason Davenport, and specialist coaches Saverio Rocca, Hamish McIntosh and Greg Williams were all made redundant. Added to the club's coaching panel in the new development role as leader of the Carlton College of Sport Development Program and Carlton Academy coach was former Western Jets and development coach Torin Baker. Long serving assistant coach John Barker, who had also served as caretaker senior coach for part of the 2015 season, departed the club in June after 10½ years, a few months earlier than his originally planned departure at the end of the season.
