- Oscar

English or IrishMeaning:
"God spear, or deer-lover or champion warrior"Description:
Oscar is one of the most stylish Old Man Names of our era. While it's softened slightly in popularity over the past 20 years, that may be considered a very good thing.

- Ottilie
Origin:
German, FrenchMeaning:
"prosperous in battle"Description:

- Otis

Variation of Otto, GermanMeaning:
"wealthy"Description:
Otis has real appeal for parents attracted to its catchy O initial and combination of strength and spunk. The appealing hero of the British TV show Sex Education has done much to propel Otis into the forefront of cool names.
- Olive
Origin:
English, from Latin, nature nameMeaning:
"olive tree"Description:
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.
- Ozias
Origin:
GreekMeaning:
"salvation"Description:
Everyone says they want an unusual name — well, if you truly do, this is one with Biblical cred that fits the bill, with the added attraction of the user-friendly nickname of Oz or Ozzie. Ozias is the name of several minor figures in the Bible. Osias is another spelling.
- Odette
Origin:
French, from GermanMeaning:
"wealthy"Description:
Odette is the good swan in Tchaikovsky's ballet Swan Lake, a role for which Natalie Portman won an Oscar ---and it would make a particularly soigne, sophisticated yet upbeat choice, unlike some of the more dated other 'ette'-ending names.
- Orson
Origin:
Latin and EnglishMeaning:
"bear cub"Description:
Orson has had in the past a rotund teddy-bear image, a la Orson Welles, who early on dropped his common given name of George in favor of his more distinctive middle one, and who seemed to own it during his lifetime. No longer a single-person signature, it's now an interesting possibility for any parent seeking an unusual yet solid name. It's started to appear to the celeb set--both Paz Vega and Lauren Ambrose have little Orsons.
- Oberon
Origin:
Variation of AuberonMeaning:
"noble, bearlike"Description:
The Shakespearean character Oberon in A Midsummer Night's Dream is King of the Fairies, but the name, with its strong 'O' beginning, projects a far more virile image than that.
- Oona
Origin:
Irish, variation of UnaMeaning:
"lamb"Description:
Oona is a name made famous by Eugene O'Neill's daughter, who became Charlie Chaplin's wife. One of the original Oona's granddaughters was named after her, and is now an actress famous in her own right for playing Talisa of Volantis in HBO's "Game of Thrones." The double-o beginning gives their name a lot of oomph.
- Orla
Origin:
IrishMeaning:
"golden princess"Description:
Orla is an Irish name closely associated with the high king Brian Boru, as it was the name of his sister, daughter and niece. It was very popular in the Middle Ages – the fourth most popular name in twelfth century Ireland – and has become popular again in Ireland, Scotland, England and Wales today. In Irish, the name is commonly spelled Orlaith or Orlagh.
- Onyx
Origin:
Gem nameDescription:
Unlike Pearl and Ruby, this is one gem name suited for boys, the final x making it sound strong and virile. Musician Iggy Azalea chose the name Onyx for her son.
- Oisin
Origin:
IrishMeaning:
"little deer"Description:
Oisin is one of the most popular Irish baby names in its native land, though largely unknown in the US. The original Oisin was the mythological son of Finn McCool and Sadb, the goddess who was changed into a deer. A legendary war hero and poet, Oisin had a name that is also reminiscent in sound of the ocean. Pronounced correctly, this name has an attractive sheen.
- Opal
Origin:
SanskritMeaning:
"gem"Description:
Opal is on the verge of a repolishing, following other jewel names like Ruby and Pearl. A Top 100 name during the first two decades of the twentieth century, the opalescent Opal has a good chance of coming back as another O-initial option.
- Odin
Origin:
Variation of Óðinn, Old NorseMeaning:
"god of frenzy; poetic fury"Description:
Odin is the name of the supreme Norse god of art, culture, wisdom, and law — who was handsome, charming, and eloquent into the bargain. The name projects a good measure of strength and power and has excellent assimilation potential.
