Molly sounds like someone you already like. It is quick to say, warm without being sugary, and old enough to carry real history while still reading as a modern first name rather than a nickname on loan from Mary.
That history is the interesting part. Molly began as a pet form of Mary, so it inherits Mary’s meanings, beloved and star of the sea, in a much lighter package. Half of everyone ever recorded with the name was born after 1994, which keeps it feeling familiar today while still reading as current for a baby.
Verdict: Molly is a strong pick for a baby born in 2026. It ranked 196th among U.S. girls in 2025, per Social Security Administration data, so everyone can spell and say it, yet there is little chance of three Mollys in one kindergarten class.
Molly Overview
- Meaning: Molly is a diminutive of Mary and carries Mary’s meanings, beloved and star of the sea. Through the Hebrew Miriam it also carries bitter or sea of bitterness, read in onomastics as rebellion or strength, and Gaelic use adds wished-for child.
- Gender: Molly is a girls’ name in the United States. Boys do appear in the federal records, but barely: 360 in total, about 0.2 percent of everyone named Molly.
- Origin: English and Irish. Medieval speakers swapped the r in Mary for an l to get Molly, the same move that turned Sarah into Sally, and the name has been used as a standalone first name in its own right since at least the 1720s.
- Pronunciation: MAH-lee, with a first syllable that rhymes with doll.
- Popularity: 196th among U.S. girls in 2025, with 1,601 girls given the name; half of everyone ever recorded as Molly was born after 1994.
- Nicknames: Mo, Moll, Lolly, Ollie, Momo, Lee.
- Variations: Mollie, Maille, Mali, Amalia, Mally.
- Namesakes: Molly Ringwald, American actress in The Breakfast Club (1985). Margaret Brown, the Denver philanthropist and Titanic survivor known as Molly Brown.
What Does Molly Mean?
Molly is primarily an English and Irish name that serves as a historic diminutive of Mary, so it shares Mary’s meanings, most notably beloved and star of the sea, the second from the Latin phrase Stella Maris.
The etymology is layered, though. Through its connection to the Hebrew name Miriam, Molly also carries bitter or sea of bitterness. In onomastics that reading is usually taken as rebellion or strength under hardship rather than as a negative trait. Gaelic use adds a softer sense, wished-for child, which is the meaning Irish families tend to quote.
Worth knowing for a parent weighing the name: none of these meanings sit on the surface the way they do with a word name like Hope or Ruby. Molly reads as friendly first, and the older meanings are there for whoever goes looking.
Where Does the Name Molly Come From?
Molly comes from Mary, by way of a medieval pronunciation habit that swapped the r for an l. English and French speakers did the same thing to Sarah to get Sally, and rhyming the result once more produced Polly out of Molly (1). Margaret took the parallel rhyming route, from Meg to Peg and then Peggy.
The medieval forms Malle and Molle sit between Mary and the modern spelling. Molly itself is not a biblical name, only a derivative of one: the line runs back through Mary to the Hebrew Miriam. By the 18th century Molly was settled in Britain and Ireland, occasionally standing in for Margaret or Martha but overwhelmingly for Mary.
The shift that matters most happened last century. Molly stopped being a nickname parents used and became the name on the birth certificate, which is how nearly every American Molly gets it today.
How Popular Is the Name Molly?
Molly ranked 196th among U.S. girls’ names in 2025, with 1,601 girls given the name, or about one girl in 1,004 (2). That puts it in the band parents usually describe as familiar but not everywhere.
The chart tells a clean story. Molly climbed steadily through the 1970s and 1980s and peaked in 1991, when 4,652 girls were named Molly and the name reached 74th, its best rank in the whole record. What followed is a gentle decline rather than a collapse: it slipped from that peak to 196th, and it has never once fallen off the list.
Two figures put that in perspective. Molly has appeared in every one of the 146 years of federal records, which begin in 1880, and 176,127 girls have been recorded with it in total. Half of everyone ever recorded with the name was born after 1994, and it has kept a steady trickle of new babies named Molly each year since.
For a parent choosing today, that combination is the appeal. A name at 196th is safe from sounding invented or trendy, and it is not climbing fast enough to feel crowded by the time a child starts school.
How Do I Pronounce Molly?
Molly is pronounced MAH-lee, two syllables, stress on the first, which rhymes with doll.
Pronunciation stays consistent across English-speaking countries, with only small vowel differences by accent. In parts of the UK the o is shorter and sharper than the drawn-out American ah. Nobody has to ask twice, and no one spells it back to you wrong, which is a practical point in the name’s favor.
Is Molly a Boy or Girl Name?
Molly is a girls’ name in the United States, and it has been for its entire recorded history. Boys do turn up in the federal data, but barely: 360 in total across every year on record, about 0.2 percent of everyone named Molly, and the most recent year with any at all was 2014, when five boys received it.
So while plenty of surname names and nature names have crossed gender lines in the last two decades, Molly has not moved. The nickname Mo works for anyone, and Ollie leans boyish, but the full name reads as female to essentially every reader.
What Are the Variations of Molly?
Mollie, Maille, Mali, Mally, and Amalia are the variations you will meet most often. Because Molly is itself a derivative, its variations tend to circle back toward Mary or amount to spelling tweaks.
- Mollie: The main alternative spelling, with a slightly more vintage feel.
- Maille: The traditional Irish and Gaelic spelling.
- Mali: A Welsh form, also found in Thai, where it means jasmine.
- Amalia: A different root entirely, but Molly is sometimes used as its nickname in German-speaking families.
- Mally: An archaic spelling, rarely given today.
What Are the Best Nicknames for Molly?

- Mo: A cool, unisex short form.
- Moll: The most intuitive shortening.
- Lolly: A playful rhyme, in the same family as the Molly to Polly rhyme that made Polly a name of its own.
- Ollie: Spunky and slightly boyish, taken from the second syllable.
- Momo: A repeating nickname that suits toddlers.
- Lee: The tail of the name on its own, for a simpler sound.

Which Names Rose and Fell With Molly?
Kayla, Samantha, and Jasmine follow Molly’s curve most closely, with Alexandra, Emily, and Brooke close behind. We set Molly against the other girls’ names of the last 45 years of birth data and looked for the ones whose yearly totals rose and eased on the same schedule, which is a different question from which names sound alike.
The three closest are the ones plotted above.
- Kayla: Peaked in 1991, the same year Molly did, took its best rank of 11th in 1995, and has fallen further since, sitting at 364th in 2025.
- Samantha: Also peaked in 1991, climbed as high as 3rd in 1998, and remains ahead of Molly at 151st in 2025.
- Jasmine: Peaked in 1993 and took its best rank, 23rd, that same year; it sits at 206th in 2025, ten places behind Molly.
- Alexandra: Best rank 26th in 1995, and 237th in 2025.
- Emily: Best rank 1st in 1996, and still the strongest of this group at 34th in 2025.
- Brooke: Best rank 43rd in 2003, and 313th in 2025.
These are our reading of public birth data, not a recommendation from anyone official. They are useful in two ways: they show which names a parent drawn to Molly is often weighing at the same time, and they make sensible sister names, since siblings with names from the same era rarely sound mismatched.
