The most established word for someone who shares your name is namesake, although it can also imply that one person or thing was named after another. In casual conversation, name twin is often clearer when you simply mean “we have the same name.”

Does “Namesake” Mean Someone With the Same Name?
Yes. Namesake can refer to a person or thing that has the same name as another. However, it is often used when there is a naming connection—for example, a child named after a grandparent—so it can sometimes suggest more than coincidence. If you only want to say that two people happen to share a name, name twin or someone who shares my name is harder to misunderstand.
Namesake
The most established single word. It works especially well when two people share a name, although readers may sometimes assume one was named after the other.
Example: I met my namesake at the conference—there were two Anthony Martins on the attendee list.
Name twin
A friendly, informal expression for someone with the same first name or full name. It makes the coincidence clear without implying that either person was named after the other.
Example: I finally met my name twin in person after years of being mixed up in emails.
Name double
An informal expression that emphasizes the duplication of the name. It is understandable but less common than “name twin.”
Example: There’s another Daniel Lee in the department—he’s my name double.
Same-name counterpart
A neutral descriptive phrase, useful when you need to distinguish two people with the same name in a formal or explanatory context.
Example: The US researcher contacted her same-name counterpart in Australia.
Someone who shares my name
Often the clearest everyday wording. It is not a special term, but it leaves no ambiguity about what you mean.
Example: I keep getting messages meant for someone who shares my name.
Terms to Avoid
Homonym normally describes words that share a spelling or pronunciation, not people who happen to have the same name. Doppelgänger usually refers to a lookalike, so “name doppelgänger” is playful rather than a standard term.
The Short Answer
Use namesake if you want an established word. Use name twin for a casual coincidence, or simply say “someone who shares my name” when clarity matters most.
