Evangelism refers preaching the Christian Gospel or to the practice of relaying information about a particular set of beliefs to others with the object of conversion.

Christians who specialize in evangelism are known as evangelists whether they are in their home communities or living as missionaries in the field. Some Christian traditions consider evangelists to be in a leadership position; they may be found preaching to large meetings or in governance roles. Christian groups who actively encourage evangelism are sometimes known as evangelistic or evangelist. The scriptures do not use the word evangelism, but evangelist is used in (the translations of) Acts 21:8, Ephesians 4:11, and 2 Timothy 4:5.

The communication of Christian faith to new geographical areas and cultures is often referred to as evangelization, or specifically, world evangelization.

The word evangelist comes from the Koine Greek word εὐαγγέλιον (transliterated as "euangelion") via Latinised "Evangelium", as used in the canonical titles of the four Gospels, authored by Matthew, Mark, Luke, and John (also known as the Four Evangelists). The Greek word εὐαγγέλιον originally meant a reward for good news given to the messenger (εὔ = "good", ἀγγέλλω = "I bring a message"; the word angel is of the same root) and later "good news".
