A messenger of good news, especially someone who preaches the Christian gospel; also refers to the gospel itself.
From Greek 'euangelion' (good news), combining 'eu-' (good) and 'angelion' (message), borrowed into Latin and then Middle English. The word originally meant any good news but became specifically associated with Christian teaching.
The same Greek root 'eu-' (good) appears in 'euphoria' and 'eulogy'—it's the prefix for all the good stuff, making 'evangel' literally a 'good-messenger.'
