What is Ted Mosby's full legal name?

Ted Mosby’s full legal name is Theodore Evelyn Mosby. He is the protagonist and future narrator of How I Met Your Mother, played by Josh Radnor.

The series begins with Future Ted telling his children the long story of how he met their mother. The younger Ted is an architect living in New York City, and his desire to find a soulmate drives the show’s central storyline. His middle name, Evelyn, is an established character detail rather than a nickname or an alternate identity.

Ted’s full name is easy to confuse because the series frequently plays with aliases and exaggerated titles. Barney, for example, gives Ted several humorous fake names, including “Ted Mosby, Architect.” Ted also uses “Doctor X” during his college radio days and is mockingly called “Teddy West-side” and other variations by friends.

Ted was born on April 25, 1978, according to the character’s biography. His children, Penny and Luke, hear the story from him in 2030, creating the show’s framing device and its distinctive future-past structure.
