George Barna (born 1954) is the founder of The Barna Group, a market research firm specializing in studying the religious beliefs and behavior of Americans, and the intersection of faith and culture. Since 2013 he has served as the Executive Director of the American Culture & Faith Institute, the research division of United in Purpose. 
Barna grew up a Catholic in New York City and Princeton, New Jersey, but has since engaged with evangelical Christianity. He graduated summa cum laude from Boston College with a Bachelor's degree in sociology (along with a minor or secondary focus in religion), and holds two master's degrees from Rutgers University and a doctorate from Dallas Baptist University.
Barna leads seminars for church leaders, speaks at ministry conferences, has taught at seminaries, and has been a pastor. As an author, he has written more than four dozen books on contemporary Christian issues, with topics ranging from worldviews, trends and children to church life, spiritual growth and leadership. He also writes columns which are published on the website of the American Culture and Faith Institute. As a result of his work, Barna has coined several terms, including:
- Mosaic Generation – the demographic profile of those born between 1984 and 2002. According to Barna, this generation is "very mosaic in every aspect of their life." He continues, "There's no attribute that really dominates like you might have seen with prior generations." Barna also describes this group as "comfortable with contradiction", "post-modern" and exhibiting "non-linear" thinking.
- Theolographics – the theological perspectives and applications of people;
- Spiritainment – a portmanteau which refers to the blending of spirituality and entertainment, toward influencing people's spiritual perspectives.
- SAGE Cons – an acronym that stands for Spiritually Active Governance Engaged Conservative Christians - the roughly 10% of the US adult population who are compelled by their commitment to Christianity and biblical obedience to be informed and involved in governance issues
Barna is known for providing extensive surveys regarding Christianity and the state of the church. Among his findings that have generated substantial interest or controversy in recent years include:
- children are the most important population segment to minister to because of their spiritual teachability and developmental vulnerability;
- God transforms people's lives in connection with a 10-stop journey that is surprisingly consistent across people groups 
- conservative Christians are eager to have their pastors teach them how to think biblically about current cultural issues, but pastors are reluctant to get involved in matters that are political and controversial; 
- Christian churches in the United States have been generally ineffective vessels for evangelism and discipleship;
- most Protestant pastors are neither called to nor competent in leadership;
- only one out of every ten American adults has a biblical worldview, including less than one out of every three born again adults;
- every church engages in marketing, but few do it well;
- mass media has the most dramatic effect on people's behavior and beliefs;
- a growing group of spiritually devout Christians, known as Revolutionaries, are embracing a post-congregational narrative that is reshaping spiritual life in the U.S.;
- most "church growth" is simply the recycling of church-goers from one congregation to another.
- divorce rate amongst born-again Christians is significantly higher than that for atheist/agnostics. A more recent 2008 Barna report shows a closer divorce rate gap between born-again Christians (32% had been divorced) and atheist/agnostics (30% had been divorced).
Barna considers Maximum Faith to be his most significant book. Others that he cites as being especially valuable include Transforming Children into Spiritual Champions, Think Like Jesus, The Power of Vision, and Revolution. Since 2009 in addition to writing his own books he has also been a writer for hire, penning books such as The Cause Within You, for Matthew Barnett, which became a New York Times bestseller in 2011.
