Baby boys' names starting with O: 38 Indian names with meanings

Indian baby boys' names starting with O

O is rare at the start of Indian names and almost always sacred when it appears — Om and its compounds account for most of them.

There are 38 here, each printed with its meaning and its Devanagari spelling where we hold one. Families usually arrive at a letter for one of three reasons: the birth nakshatra's pada suggests a syllable, a grandparent's name begins with it, or the family simply likes how it sounds with the surname.

Every name comes from our verified name corpus — the editorial workbooks our team maintains, cross-checked against United States birth-registration data. Names we hold no meaning for are left out rather than padded in, which is why this list is shorter than the ones that scrape a dictionary.

The O names families are actually using

These are the names on this page that show up in United States birth registrations for 2025 — a real signal of which spellings Indian families abroad are registering now. India has no comparable public register, so anyone ranking names within India is estimating.

Choosing between them

Say the shortlist with the surname, out loud, several times. A name that is lovely alone can be unsayable in full, and the full version is what a teacher will read from a register.

Fix the spelling before you register the birth. Romanised Indian names have several accepted spellings — the one on the birth certificate has to match the school record, the passport and the Aadhaar that follow it, and correcting them later is genuinely painful.

If your family follows the panchang, the birth nakshatra's pada decides the traditional syllable. Our birth star calculator gives the star, the pada and its syllable from the date and time of birth — start there, then look for a name on this page that fits.

And check the short form and the initials, because those are what the child will actually be called.

Frequently asked questions

Q: How many boys' names starting with O are on this page? — 38, each with a recorded meaning. Names whose meaning we cannot verify are not listed.

Q: Which is the most used? — Of the names here, Oakley (oak clearing) has the highest 2025 US birth count. Within India, popularity varies a great deal by state and community.

Q: Is my baby's nakshatra syllable the same as this letter? — Not necessarily. The panchang syllables are written in Devanagari and do not map one-to-one onto English letters — "Ch", "Sh" and "Th" are single sounds, for instance. Use the birth star calculator for the syllable, then match it to the Devanagari spellings in the table.

Q: Do you have girls' names for this letter? — Yes, on its own page, along with lists for the other letters and for names grouped by meaning.
