The Hong Kong Federation of Youth Groups (HKFYG) is the city's largest youth service organisation. Since its establishment in 1960, the HKFYG has been providing opportunities and facilities for the social, educational, cultural and physical development of young people. Income is obtained primarily from government subvention, as well as grants from the Community Chest of Hong Kong, the Hong Kong Jockey Club Charities Trust, other trust funds, programme fees, and both private and corporate donations.

The HKFYG, through its youth membership network, provides quality services that address the issues and concerns of young people and promotes healthy all-round development. Over 70 service units organise more than 20,000 activities annually, with attendance to the various programmes now standing at five million a year. Over 400,000 registered members are engaged through the online platform, easymember.hk and the HKFYG app.
