The Gospel of Luke is an anonymous text. Church tradition identifies its author as Luke, a companion of Paul and a physician, but this identification is extra-textual and not supported internally. The author, who also wrote the Acts of the Apostles, was a Greek-speaking Gentile Christian writing for a Gentile audience, as evidenced by his explanations of Jewish customs and use of the Septuagint. He was not an eyewitness but compiled his narrative from earlier sources, including the Gospel of Mark. The work is generally dated to c. 80–90 CE.

The Gospel of Luke is a narrative of the life, ministry, death, and resurrection of Jesus of Nazareth, forming the first part of the two-volume Luke-Acts.

As one of the four canonical gospels, Luke is a primary source for the life of Jesus. It is notable for its literary structure, its emphasis on universal salvation, and its focus on themes like prayer, the Holy Spirit, and concern for the marginalized. Its parables and narratives have been profoundly influential in Christian thought and culture.
