O o

For the seriously audacious biblical baby namer who wants to move beyond Elijah and Josiah, this name has considerable old-fangled charm. Obadiah, who gave his name to one of the shortest books in the Bible, was a rich man who had the gift of prophecy. There are several other men named Obadiah in the Bible, as well as a Saint Obadiah. There have been two prominent U.S. senators named Obadiah.

The surname of the 44th US President has been been adopted as a first, for girls as well as boys, by admiring parents around the world. And the O beginning even makes it fashionable.

The name appeared in the US stats in 2024 for the first time since the late 60s, when it was given to 6 boys.

Though greatly overshadowed by the trendy Olivia, Olive has a quiet, subtle appeal of its own -- and is now enjoying a remarkable comeback. Olive is one of only four girl names starting with O on the US Top 1000. Cool couple Isla Fisher and Sacha Baron Cohen chose it for their daughter, reviving the name to stylishness, and now Drew Barrymore has a little Olive too, as has country singer Jake Owen.

Oliver is an international star, ranking near the top of the charts throughout the English-speaking world and in a host of European and Latin American countries, from Norway to Chile, Slovenia to Switzerland. Why? Because Oliver is energetic and good-natured, stylish but classic, with a meaning symbolizing peace and fruitfulness.

Floral, elegant, and bold, Ophelia re-entered the US Top 1000 in 2015 after more than 50 years off the charts. It has risen more than 700 spots since then and shows no signs of slowing down. Now in the US Top 300, could Ophelia one day become the next Olivia or Amelia?

Wears long blonde braids, carries a spear, and sings duets with Brunhild. But variations Ottilie, Ottiline, or Ottoline are both unusual and chic.

Owen, a resonant Celtic name, has ranked among the Top 100 boys' names in the US for 20 years and is now at its highest point ever.
