baby name DexterThe baby name Dexter combines a preppy polish with a heck of an edge.

Thanks to Kayt and Natalie for suggesting today’s Name of the Day.


The baby name Dexter started out as a surname, from dyster – a medieval English occupational name for one who dyed wool. The wool industry was massive in the era; England exported sacks and sacks of it, both as raw material and finished cloth.

No surprise, then, that the surname Dexter caught on. And, like nearly any familiar surname, was sometimes given as a first, too.

But there’s a second meaning to the baby name Dexter.

In Latin dexter means skillful. Think of the word dexterous.

Over the years, it meant both nimble with one’s hands, and also clever and quick-witted. It’s an appealing image for a child’s name.


And yet, the baby name Dexter has always been on the fringes – more common as a last than a first.

It has appeared in the US Top 1000 every year since 1905 – and many years before that, too.

The name spiked a few times, reaching #262 in 1968 and #317 in 1987 and #361 in 2012.

But even those highs aren’t very.


One unforgettable Dexter: the dashing CK Dexter Haven in The Philadelphia Story.

The 1939 Broadway play became a hit 1940 movie. Katharine Hepburn played socialite and bride-to-be Tracy Samantha Lord. Cary Grant played CK Dexter Haven, her first love – and ex-husband. James Stewart played another of Tracy’s suitors, and won a Best Actor Oscar for the role. (Hepburn was also nominated.)

Tracy calls CK Dexter Haven “Dex” most of the time.

It’s easy to fall in love with the name, especially after the couple lives happily ever after.

(And yes, the movie almost certainly gets credit for launching Tracy as a girl’s name. But that’s another post …)


Between the 1940s and the twenty-first century, a handful of notables wore Dexter as a first or last name.

That list includes character actors, like Alan Dexter and Brad Dexter.

Grammy-winning jazz saxophonist Dexter Gordon’s long career spanned from the 1940s into 1980s. He also established himself as an actor, earning an Oscar nomination for his portrayal of – what else? – a jazz musician in 1986 movie Round Midnight. (Fun fact: Gordon lived in Denmark for many years and served as godfather to Lars Ulrich of Metallica.)

Martin Luther King Jr.’s son, Dexter Scott King, was just seven when his father was assassinated. The civil rights leader’s tragic death put his entire family’s names in the headlines – and likely explains the 1968 peak for the baby name Dexter.


In 1995, we met boy genius Dexter on Cartoon Network. The star of Dexter’s Lab toiled in his secret laboratory while his sister Dee Dee and arch-rival Mandark foiled his plans. The series ran through 2003.

The animated series did nothing to revive the name. If anything, it cemented the sometimes-image of the baby name Dexter as a nerdy intellectual.

Where did the image originate? The French surname Poindexter literally means “right fist – it feels pretty tough guy. But the Felix the Cat cartoon gave us a super-genius kid by the name from 1959 to 1962. The image stuck, and almost certainly informed the naming of Dexter’s Lab. But it wasn’t the only one. Arnold Poindexter appeared in the original Revenge of the Nerds movie. (He’s the violinist.)

In 2004, Jeff Lindsey published his first Dexter Morgan novel. Showtime debuted Dexter in 2006, and it ran for eight critically acclaimed seasons.

Lindsay’s Dexter earns his living as a Miami police expert, but moonlights as a serial killer. The twist? Dexter brings vigilante justice to those who escape the reaches of the law.

The series was wildly popular, and it tracks neatly with the name’s resurgence, too. In 2006, the baby name Dexter sat at a chilly #916. By the time the show’s final episode aired in 2013, Dexter ranked #382.


So we named our sons after a serial killer with a moral compass. That’s not such a surprise – villain names catch on all the time.

Or maybe parents were just drawn to the letter X and the -r ending. After all, the baby name Dexter combines some of the best elements of Jax and Carter, Alex and Ryder. But it also feels like more of a vintage choice, a brother for Theodore or Calvin.

After decades as a steadily obscure choice, the baby name Dexter feels slightly more familiar now. Though as of 2019, it stood at #464 – that’s not exactly Liam or Noah.

But with an on-trend sound and cool nickname Dex, it’s easy to imagine the baby name Dexter wearing well on a son born today.

  1. I must confess I like Dexter for a son of mine, *because* of the serial killer. Then again, I’d also want a little Damien, my family’s terrified.

  2. I really love Dexter, on someone else’s child. My husband and I have seen every episode of the TV show about the serial killer Dexter and so have all of our friends and family, so we could never use it. Hubby loves the show so much he doesn’t think we could even use it for a dog, the association is that strong! But I will always have a soft spot for Dexter 🙂 And Dex is just the best nn ever!

  3. I don’t like Dexter. I think of Dexter’s Lab when I hear it and I don’t go naming kids after cartoon characters. I’d probably save it for a dog or a cat if I ever decided to use it. I knew a Dexter in 9th and 10th grade and he was pretty geeky, nice boy though. It isn’t a bad name, It’s just too nerdy to me. It also reminds me of the Jak and Daxter video games.

    I heard about Diane Keaton’s daughter too. I was like “WTF?! Dexter is not a girl’s name!” Boys names don’t belong on girls. It’s horrible! Whoever started that trend is really messed up in the head. No offense to anyone who likes trendy names, but I can’t stand a majority of them. They are way overrated. I have a feeling that Dexter will probably become trendy soon if it already isn’t.

  4. I really love this name.
    I never really thought about it until my younger sister mentioned that a girl in her school (Daisy) has a little sister named Scarlett and yes a baby brother named Dexter – i fell in love with it immediately!

  5. I *never* forget Archibald Leach turning into Cary Grant! Archibald was my favorite name when I was 6 years old. I had three teddy bears, two alligators and a real hamster named Archibald at the time. My mother thought I was nuts! 😀 “A Fish Called Wanda” had an Archibald Leach (played by my beloved John Cleese) in it.. One of my top 5 movies of all time.

  6. Thank you! I just adore Dexter. If my in-laws hadn’t thoroughly beat him into the ground, I think my husband would consider him for a second boy option. As silly as it sounds, I hesitate to use him as a second boy option because I want to use my maiden name for a second boy’s middle name, and I abhor the sound of Dexter Calder. I want to meet more Dexters, though. It’s so so cool!

  7. I like my boys stuffy, geeky and/or moldy. Dexter fits Geeky/Stuffy pretty easily and yes, I really like him. Dex makes me think briefly of “Dexy’s Midnight Runners” & “Come on Eileen” but that thought makes me smile for my long ago teenage years. 🙂
    Dexter’s jazzy, snappy and feels happy. Smart too. If he didn’t feel so surnamey to me, he’s be on my own list. But I really like Dexter and would admire it on anyone else’s little boy! He’s aces!
