With its gentle sounds and earthy vibes, the name Rowan feels like a fusion of different styles. A word name, a surname, and a gender-neutral name, Rowan is rustic but trendy, blending the vibes of both Owen and Oakley.

Robert was the Number 1 boys' name in the US in both 1925 and 1950, and in fact was in the Top 25 for more than a century, giving it true classic status. Strong if not quite stylish, Robert remains in the Top 100 for baby boys as a family favorite.

Ryan’s use as a given name was inspired by the surname Ryan, a variation of the Irish O’Riain meaning "son of Rían." Rían is composed of the Irish-Gaelic elements rí, meaning "king" and an, a diminutive suffix. Ryan is considered a unisex name in the US, where variant spellings Ryann and Ryanne are also valid for girls.

River shares the tranquil feeling of all the water names, and seems to have pretty much escaped its past strong association with River Phoenix and his unfortunate fate. Actor Joaquin Phoenix named his son with actress Rooney Mara after his brother River.

This spirited Gaelic classic, which became popular in Ireland via the illustrious twelfth century king Rory O'Connor, makes a highly energetic choice, now used for either sex. Rory's gender split is still trending boyward; it's one of the coolest boys' names starting with R.

Riley -- one of the most popular unisex names -- is trendier now for girls though for boys it's a classic, ALWAYS ranking in the US Top 1000.

The Reid spelling is the most popular by half, probably because it feels more like a name than Reed, which looks more like a word. It's used occasionally for girls but this name is firmly in the boys' camp.

One of many R- boys' names that started as a nickname for a redhead, Russell had a measure of popularity from the early twentieth century through the 1950s. After a low point in the 2010s, Russell is starting to regain its color. For many parents, it's an ideal sweet spot name — a traditional choice that's familiar, yet not overly popular.

Rugged but gentle, Rhys is the traditional Welsh spelling of this name, which can also be anglicized as Reese or Reece. Up until 2010, Reese was the preferred spelling in the US, perhaps because parents were concerned about mispronunciation. However, Rhys has since taken over for boys and is now used twice as often as Reese.

Even less subtle than Duke or Earl, this name shot up the popularity charts in 2013, the same year young Prince George was born and the craze for all things royal (and Royal) began. Today, it's a leading boys' name on Nameberry's own popularity charts.

Ridge may be the quintessential daytime drama name, but it's still better than most. This is one word name rising rapidly through the ranks, reentering the US Top 1000 in 2015 for the first time since 1989.

Rio is a reductive ranchero place-name with an attractive Tex-Mex lilt. No Doubt's Tom Dumont has a son named Rio Atticus.

A popular choice back in the 50s and 70s, Rocky fell into decline after Sylvester Stallone's battered but not beaten boxer character became the overwhelming association many had with the name. Now, nearly five decades on from when the first Rocky movie was released, this tough yet playful name is back in style, ready to forge an identity of its own. Given to around 420 boys in the US in a recent year, it was one of the fastest rising names in the charts.

An Anglicized spelling of the Welsh Rhys, this traditional boys' name got a big boost for girls in the early 2000s, thanks to the high-profile Ms. Witherspoon (who was actually born Laura Jeanne Reese, her second middle being her mother's maiden name). This spelling has been on the decline for boys since 2003, possibly for the same reason, but remains a strong, simple choice which might pose fewer spelling and pronunciation issues outside of the UK than the Welsh original.

Gentle but solid, as much of a word as it is a name, Robin is a rising star in the US, and a favorite in Belgium, France, Czechia and Switzerland. With memorable namesakes like Robin Hood, Robin Williams, Christopher Robin, and Robin the Boy Wonder, a recent year saw Robin feature as a gender neutral choice in the US, ranking at #703 for boys and #704 for girls.

Rudy is one of those names that has been consistently in the US Top 1000 since the early 20th century without ever becoming overwhelmingly popular. It peaked back in the 1930s, when it briefly entered the Top 250, though more recent years have seen it make the latter end of the charts. Certainly more stylish than its parent name, Rudolph, which has been relegated to reindeers in English speaking countries, Rudy was given to 300 boys in a recent year.

Simple, short, and cool, Ray gives off retro vibes thanks to its 20th century popularity, and its links to jazzy Ray Charles and Ray-Ban sunglasses. A popular middle name for boys, it is well established as a given name too.

Now that many dogs are named Max, it's safe to use this sleek, solid, regal name again for your child. And with the charm of its final x, its regal meaning, and its offbeat simplicity, Rex is definitely one to consider.

Rock definitely has a macho image, if a somewhat caricatured one, ala The Rock. But with the rise of word names and also of tough guy names, Rock feels more plausible than it did a generation ago.

Russel is a masculine name derived from the French surname 'Roussel,' meaning 'little red one' or 'red-haired.' This spelling variation (with one 'l' instead of the more common 'Russell') emerged in English-speaking countries and has maintained consistent, though modest, usage. The name carries associations with the color red, suggesting vitality and strength. Historically, Russel transitioned from a surname to a given name during the 19th century, following the trend of adopting family names as first names. The name projects reliability and steadfastness, with a classic feel that avoids trendiness. Russel has never been among the most popular names but maintains steady recognition. Notable bearers include philosophers, athletes, and actors, adding intellectual and cultural dimensions to the name's character. Common nicknames include Russ or Rusty.
