AD 144 refers to the year 144 in the Anno Domini (AD) or Common Era (CE) calendar. It was a leap year starting on Tuesday (link will display the full Julian calendar) of the Julian calendar.

Events:

• Roman Empire: Construction begins on the Antonine Wall in Britannia, ordered by Emperor Antoninus Pius. This wall was intended to replace Hadrian's Wall as the northern border of Roman Britain, though it was later abandoned.
• Religious: Marcion, a prominent early Christian leader, is excommunicated from the church in Rome due to his theological views, which were considered heretical by orthodox Christians. This marks a significant development in the formation of Christian doctrine and the separation of what became known as Gnostic beliefs from mainstream Christianity.
• Potentially the death of Pope Pius I, although dating of early Popes remains inconsistent and unreliable.
