Youth ministry, also commonly referred to as youth group, is an age-specific religious ministry of faith groups or other religious organizations, usually from ages 12 to 30, whose mission is to involve and engage with young people who attend their places of worship, or who live in their community. Christian youth ministry usually encompasses one or more of the following:

• encouraging young people (whether they have professed a faith or not) to learn more about a given faith and to become more involved in spiritual life
• providing open youth clubs or other activities for the common good of the young people, sometimes without an overtly religious agenda

The doctrine of Sunday Sabbatarianism held by many Christian denominations encourages practices such as Sunday School attendance as it teaches that the entirety of the Lord's Day should be devoted to God; as such many children and teenagers often return to church in the late afternoon for youth group before attending an evening service of worship.

Youth ministry often consists of students in sixth grade though twelfth grade and adult leaders. Every youth ministry is structured differently and the culture will vary among youth ministries depending on how the ministry cultivates culture. Some youth ministries are also student led where students take on the responsibility of planning services.
