About the letter O
The most common is Olivia, with roughly 661,958 people in the United States. Of the 532 O names on record, 423 are carried by fewer than a thousand people each — the long tail that makes up most of any letter.
This page lists the 500 most common. To go further, or to filter O names by length, syllables, gender or era, use the advanced name search. Every name here links through to its full profile: how many people carry it, its age profile, where it is concentrated and how it has moved since 1880.
