Nicknames for Someone with III in Their Name: 40+ Cute, Funny & Unique Options (2026)

Introduction

The Roman numeral III at the end of a name traditionally marks a third-generation namesake—someone who shares their full name with a grandfather and father. While “III” is a formal suffix, many people with III in their name adopt nicknames that play on the number three, the word “third,” or the initial sounds of their first name. The most classic nickname for III is Trey, derived from the old English word for three. But there are dozens of other options ranging from affectionate and cute to humorous and modern. This guide covers over 40 nickname ideas organized by style, so you can find the right fit for the III in your life.

Classic III Nicknames

• Third – Straightforward and clear. Works well in both formal and informal settings, especially in writing or introductions.
• Tre – A short, modern take on the number three. Pronounced like “tray,” it offers a sleek, minimalist feel.
• III (eye-eye-eye) – Pronouncing the Roman numerals as three letters is a playful, inside-joke nickname that only those close to the person might use.
• The Third – A semi-formal nod that can be used affectionately in speech, e.g., “Here comes the Third.”
