Final answer:
The disciples of Jesus were first called "Christians" in the city of Antioch.
Step-by-step explanation:
The town where the disciples of Jesus were first called "Christians" is mentioned in the Bible in the book of Acts 11:26. It states that the term "Christian" was first used to describe the followers of Jesus in the city of Antioch. Antioch was an important city in the Roman Empire, located in modern-day Turkey. The term "Christian" is derived from the Greek word "Christos," which means "anointed one." The disciples of Jesus began to be called Christians because they believed that Jesus was the Messiah, the anointed one who came to save humanity.
