60+ Rare and Unique C Names for Boys

Ryan Brennan04/16/25

When you think of boy names that start with C, what’s the first name that comes to mind? 

Most American parents would say Christopher or Charles, which have ranked 10th and 11th in popularity, respectively, over the last 100 years (since 1924).

According to the Social Security Administration (SSA), Christopher and Charles have accounted for more than four million births over that 100-year span. 

But that, of course, is just the beginning of what C boy names have to offer. 

After all, the letter “c” has been a top-5 first initial for boy names every year since 1970, per Behind the Name, and most recently accounted for more than 6.4% of all names given to baby boys in 2023. 

And Charles and Christopher aren’t even the most popular C names for boys today. 

While they still ranked 54th and 55th in 2023, respectively, the most popular C boy names today are, instead, Carter (48th), Caleb (51st) and Cooper (52nd).

In fact, Cameron (58th), Christian (77th) and Colton (94) were the only other boy names with C included in the SSA’s top-100 for 2023. 

So, that begs the question — where are all those unique and rare boy names that start with C? Well, let’s find out!
