If you know a Ruby, plain old Ruby probably isn’t the only thing people call her. Nicknames for Ruby run from short everyday shortenings to funny ones her friends made up on the spot to romantic ones her partner would never say in front of anyone else. Some fit a toddler still learning to say her own name. Others fit a grown woman who runs a household, a business, or both.
This list pulls together the classics that show up in classrooms and offices, plus newer spins born in group chats, sports teams, and inside jokes. If you’re naming a new baby, looking for something to call your girlfriend, or just trying to tease your sister a little, there’s something here that fits.
Where the Name Ruby Comes From
Ruby comes directly from the gemstone of the same name, which itself traces back to the Latin word rubeus, meaning red. The ruby has long been prized as one of the most valuable gemstones, historically associated with passion, protection, and vitality, which gives the name Ruby a rich, vivid meaning tied to both color and strength.
The name has stayed popular in the United States for well over a century, often peaking during eras when vintage, old fashioned names come back into style. It carries a warm, old soul charm while still feeling fresh, which is part of why Ruby has remained a steady favorite across generations of American parents.
Because Ruby is rooted in a gemstone, nicknames for it tend to split a few ways. Some lean into the jewel connection, playing on red, shine, and sparkle. Others simply shorten the name itself or build on its sound for something softer or bolder.

Conclusion
At the end of the day, a nickname is really just a name that fits how someone actually feels to the people around them. Some Rubys will always be Ru to their family and something completely different to their friends, and that’s exactly how it should work. The right Ruby nicknames aren’t the ones that sound the best on paper, they’re the ones that stick without anyone forcing them.
If none of these feel quite right yet, that’s normal. A lot of great nicknames come out of a moment, a joke, or a habit that just kept going, not a list. Use this one as a starting point, try a few out loud, and let the one that fits find its way in on its own.
A classic shortening like Ru, something sweet like Roo Boo, or a completely invented spin like Rubyska all aim at the same goal, something that feels like her, and that she’d actually want to be called.
