Leo is a strong-yet-friendly name that was common among the Romans, used for fourteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

According to exclusive Nameberry data, Logan is officially the Number 1 gender-neutral name in the US, but that statistic is somewhat misleading given that nearly 90 percent of the baby Logans born in 2024 were boys.

Loyal is one of the few virtue names suitable for boys, an honorable and principled Boy Scout-esque appellation with a surprisingly long and distinguished history.

Lewis is the best spelling to choose if you want this pronounced with the S. It was a Top 100 name in the US from 1880 to 1930, reaching Number 30 in 1880 and while it has declined in use, it has remained in the Top 1000 since stats began.

Lawrence has survived from Roman times, when Laurentium was a city noted for its laurel trees (the laurel is a symbol of wisdom and achievement). It was in the Top 50 from the 1890s through the 1950s and the Top 100 for decades longer, always among the most popular boys' names starting with L, but Lawrence is now used less for babies than Landon or Lorenzo.

Latinizing Lawrence gives it a whole new lease on life. Like Leonardo, Lorenzo has been integrated into the American stockpot of names, partly via actor Lorenzo Lamas. Other associations are with Lorenzo de' Medici, the Florentine Renaissance merchant prince and art patron, Renaissance artists Ghiberti and Lotto, and the upstanding young man who married Shylock's daughter Jessica in Shakespeare's The Merchant of Venice.

Popular in the first half of the 20th century, Leland briefly fell out of favor in the late 90s. After a short break from the US charts, it returned in the mid-2000s, with actor Brendan Fraser choosing it for his youngest son, possibly making it feel cool again. Given to around 500 boys each year, Leland is in the Top 600.

Leif is one of the most recognizable Scandinavian names, thanks to Icelandic explorer Leif Erikson, and is still one of the best, with a pleasant aural association with the word leaf.

The graceful, natural image of the verdant shade tree transcends any connection with President Johnson.

Typically spelled as Lonán in Ireland, Lonan is its Manx form, though it could also be considered the anglicized form too. The name comes from the Irish lon meaning "blackbird", paired with a diminutive suffix, making this a charming nature-related choice that could make a nice Logan/Conan alternative.

This cool and quirky short form of the suave Ludovic could be an even-more-adventurous spin on Nico and Hugo.

Lowell is an upstanding and somewhat conservative name that calls to mind the genteel patrician families of nineteenth century New England, such as the one poet Robert Lowell was born into. Two other Lowell-surnamed poets are Amy and James Russell.

Once restricted to evangelical Protestants honoring the ecclesiastical reformer and theologian Martin Luther, leader of the Protestant revolution. In more recent times it has been favored by parents wishing to honor civil rights hero Martin Luther King Jr. Luther was a Top 100 name at the turn of the last century, but fell off the list in the early 1990s.
Luther Burbank was an eminent botanist and Luther Vandross was a popular R&B artist. It's the name of a main character on the Disney series Zeke and Luther. The name was given a shot of contemporary energy via Idris Elba's dynamic performance in the eponymous BBC crime drama.

Leroy's heyday was in the early twentieth century, when it was in the US Top 100 until 1949. As a result, it's now more frequently seen as a father or grandfather name. Nevertheless, it remains in the latter end of the US Top 1000, perhaps passed down from father to son, or similar enough to popular Levi that it still appeals.

One of the fierce new animal names new to name lists, helped by its strong x-ending.

Lux, one of the light-filled names that include Lucy and Lucian, broke onto the scene as a girls' name but now it's decidedly gender neutral. In fact, at the last count there were slightly more boys named Lux than girls: 140 to 120. But that's pretty close, making this a truly nonbinary name.

Lupin is an unusual flower name with roots in Old French, from the Latin lupinus, meaning "pertaining to the wolf". In the literary world, it's the surname of Remus Lupin, a popular character in the Harry Potter franchise and a werewolf.

Half-way between Logan and Rowan, Lowan could be an interesting pick for parents looking for an off-the-beaten-track nature name.

Swaggering western place-name with a lot of cowboy bravado and panache.

Legend joins cousins Story, Saga and Fable in the baby name pantheon of narrative words. Unlike Story and Fable, however, Legend comes with additional weight, being used for fame ("living legend") and to denote a person who is fantastic "what a legend"). Who can live up to that?
