21 Cool September Baby Names

We love September for the changes it brings: leaves turn to their beautiful yellow-orange fall color, the weather becomes colder, and many plants start their harvest season. Summer is over, and we just want to snuggle up with a cup of hot cocoa in front of the fireplace. Meanwhile, baby names for this month are related to autumn, trees, gemstones, saints, occupations, red, and blue.

If you’re due to give birth this month, we’ve come up with 21 charming names for your baby.

September Baby Names For Boys 


This name has Latin origins and means ‘dark one.’

Wondering why it’s on our list? Saint Adrian’s (or Hadrian) Feast Day is on the eighth of September. He was a guard of the Roman Emperor Galerius Maximian who was punished when he and his wife, Natalia, embraced Christianity.


If you’re looking for a modern name that’s inspired by Labor Day (or because you’re already having contractions), choose Bailey. This gender-neutral name has its roots in Old English and means ‘bailiff’ and ‘berry wood.’ Perfect for autumn too!


How about Cooper for your little trooper? This unisex baby name is pretty popular for boys. It’s derived from English and means ‘barrel maker.’


Another boy name inspired by a saint is Cosmo, after Saint Cosmas, the patron saint of pharmacists. His feast day is on the twenty-seventh of September. This name comes from the Old Greek word, ‘kosmos,’ which means ‘order, harmony, beauty, and universe.’

We think it’s a cute yet modern name for a baby boy since Cosmo is short for Cosmopolitan, a popular fashion magazine, and a cocktail drink.

By the way, Cosima is the female version of Cosmo.


If you’re a basketball enthusiast, you’d probably associate this name with Kevin Garnett, who is recognized as one of the greatest power forwards in NBA history.

But Garnet is on our September list because it’s an occupational name that means, ‘one who makes hinges’ in Old French. It’s also the name of a gemstone that’s dark red in color.


Love autumn sunsets? Go for Harkin, a unique Irish name that also means ‘dark red.’


Since September is the ninth month of the Julian calendar, the Gregorian calendar’s precursor, we figured it belongs to our list. This trendy gender-neutral name is the Latin nickname of Julianus. It means ‘Jupiter’s child, downy.’


This name means ‘pine tree’ in German. It’s become quite well-known thanks to Hollywood actor Kiefer Sutherland, who got it from the surname of his father’s friend.


Lyndon is a place name from a county in the East Midlands of England. Its origin is Old English, and it means ‘lime tree.’ Also called Linden, these trees don’t actually bear the lime fruit.


Looking for something inspired by fall but a little less common? Patrin would be an excellent choice. It’s from English and means ‘leaf trail.’


September Baby Names For Girls


While Amber is technically unisex, it’s more popularly used for girls. This name comes from the Arabic language. It’s a yellow-orange plant resin that oozes from ancient trees. These days, amber is known as a gemstone used in jewelry.


Since fall starts in September, why not have Autumn for your baby girl’s name? This name is from the Latin word, ‘autumnus.’ Did you know that autumn was once known as ‘harvest?’


Fancy naming your daughter after a color? Consider Azure which is French for ‘sky blue.’


Aster is the birth flower for September. This unique name would be perfect for your little ‘star.’ It’s a variant of the name Astrid, which is more popular.


This widely used name means ‘laurel tree.’ Your daughter would have the same name as the nymph who was turned to a laurel tree by her father to be safe from Apollo, the God of war, in Greek mythology.


This unisex name has its name in Old English and means ‘harp player.’ Perhaps it’ll inspire your little one to learn to play this wonderful instrument someday.


This name stems from Old Greek and means ‘blossom.’ We hope your daughter blossoms into a beautiful young lady one day.


This biblical name comes from the word ‘phoibos’ meaning ‘bright, pure.’ We included it on the list since Saint Phoebe, a first-century deaconess has her feast day on the third of September.


For a modern name that stands out, add Roux to your shortlist. This name means ‘red-haired woman’ in French.


Sapphire is the birthstone for September and comes from Old Greek ‘sappheire.’ This blue gemstone symbolizes loyalty and trust.


This English name is the name of a tree with slender and pliant branches. While the name sounds gentle, willows are known for their tenacity to live in harsh conditions. Who knows? This name might endow your daughter with the same resilience.
