Boys' names with O

Almost every fiftyfive boy's first name in the USA begins with the letter O…

This means that the initial O is found much less frequently than average. On average, each letter appears as an initial in about 3.8 % of all boys' names, considering the 26-letter English alphabet. The distribution of initial letters is undoubtedly uneven – after all, some letters occur much more frequently, while others are much less frequent. In the US, the most common initials among boys' first names are J and A, while the letters U and X, on the other hand, are initials for very few names.

In the US, Oliver is currently the number 1 most popular boys’ name to start with an O. In second and third place are names such as Owen and Oscar. A far rarer name starting with O in the US is Otto.
