Luke the Evangelist (Ancient Greek: Λουκᾶς, Loukás) is a character in the New Testament. He is mentioned in three of the Pauline Epistles including Colossians where he is described by Paul as "Our dear friend Luke, the doctor" (NIV). Early Church Fathers such as Jerome and Eusebius claimed that he was the author of the Gospel of Luke and the Acts of the Apostles and this is the traditional Christian view today.

He is venerated as Saint Luke, patron saint of artists, physicians, surgeons, students, butchers; his feast day is 18 October.
