Jehovah's Witnesses are organized hierarchically, and are led by the Governing Body of Jehovah's Witnesses from the Watch Tower Society's headquarters in Warwick, New York. The Governing Body, along with other "helpers", are organized into six committees responsible for various administrative functions within the global Witness community, including publication, assembly programs and evangelizing activity.

Jehovah's Witnesses is a nontrinitarian, millenarian, restorationist Christian denomination. As of 2023, the group reported approximately 8.6 million members involved in evangelism, with around 20.5 million attending the annual Memorial of Christ's death. Jehovah's Witnesses believe that the destruction of the present world system at Armageddon is imminent, and the establishment of God's kingdom over earth is the only solution to all of humanity's problems.
