History & Origin

Tommy is a diminutive of Thomas, from Aramaic Ta'oma, meaning twin. Thomas was one of the twelve apostles of Jesus and is prominent in the Gospel of John as the apostle who initially doubted the resurrection — hence the phrase doubting Thomas. Thomas became one of the most popular names in medieval Christian Europe.

Tommy as a standalone name has been popular in the English-speaking world since the 19th century. It was a top-100 U.S. boys' name through much of the mid-20th century. The name has a notably cheerful, approachable quality and is associated with characters from literature (The Who's Tommy) and film. Today Tommy is staging a quiet revival as parents turn to friendly short-form names.

Did you know? British soldiers in World War I were commonly called Tommy Atkins — a generic name used since at least the Napoleonic era to refer to ordinary British infantrymen, giving Tommy a deep association with everyday heroism.
