The Citizen Athletic Association (Chinese: 公民體育會), simply known as Citizen or TCAA, is a Hong Kong athletic club, based in Tsing Yi. Its football team (Chinese: 公民足球隊) currently competes in the Hong Kong First Division.
Citizen won the 2010–11 Senior Shield by beating South China in the final after penalty kicks, thus earning the club the right to represent Hong Kong in the 2012 AFC Cup. To celebrate this victory, the club announced a prize fund of HK$800,000 (approx US$100,000), an iPhone 4 for every player and an end-of-season vacation for the whole team.
The club moved from the remote Siu Sai Wan Sports Ground to the renovated Mong Kok Stadium for the 2011-12 Hong Kong First Division League season. To compete in both local football and AFC Cup, Citizen has expanded its squad to include 27 players, adding Michael Campion, So Loi Keung, Chiu Chun Kit, Amaury Nunes and Yuto Nakamura to the club, while promoting two young players Chan Si-Chun and Yeung Ho Wan. Citizen is spending an unprecedented HK$400,000 on the team's 12 days pre-season training camp in Vancouver, Canada, during which time the club will play 3 warm-up games. The club announced on 7 September that Rasonic has become its new shirt sponsor for the 2011–12 and 2012–13 seasons. The sponsorship is worth HK$1 million.
