Sienna was a color long before it was a name. It is the earth pigment that gave Renaissance painters their warm browns, dug from the hills around a walled city in Tuscany, and it arrived in English as a paint before any parent thought to write it on a birth certificate.
That double life is why the name reads as artistic and grounded at the same time. It sounds Italian without being hard to spell, it sits comfortably beside classroom staples like Sophia and Isabella, and it still feels like a decision rather than a default.
Verdict: Sienna is a strong pick for a baby born in 2026. Nobody will ask you to repeat it, nobody will need it spelled twice, and it reached its highest rank on record in the most recent year of federal birth data, so it is on the way up rather than fading out.

What Does Sienna Mean?
Sienna means Siena earth, the name of a natural clay pigment taken from the Italian phrase terra di Siena. The color it names runs from a yellow-brown in the raw clay to a warm red-brown once that clay has been roasted.
The chemistry behind those two shades is simple. The clay owes its color to iron oxide, with smaller amounts of manganese minerals mixed through quartz and ordinary earth, and heating drives the water out of the yellow iron minerals and turns them red. That single step is the whole difference between the two paints on an artist’s palette, raw sienna and burnt sienna.
It is also one of the oldest colors people have used. Sienna shows up in cave paintings roughly 40,000 years old and stayed in the kit through the Renaissance, where Vasari, Caravaggio and Rembrandt all reached for it (1). So the name carries a quiet association with making things: warm earth, worked by hand, holding its color for a very long time.
Where Does the Name Sienna Come From?
Sienna comes from Siena, the hill city in Tuscany, and from the clay dug in the ground around it. The site was an Etruscan settlement first and then the Roman town of Sena Julia, and local legend hands the founding to Senio, a son of Remus (2).
The word travelled into English as a paint, not as a name. Sienna was first recorded in English in 1760, according to the pigment history kept by the color maker Winsor and Newton, and it took another two centuries before American parents began using it for daughters. Federal birth records list the first Siennas in 1960.
That order of events matters for how the name reads today. It is a color name and a place name at once, which is why it can point at something concrete without sounding literal the way Rose or Sky can.
How Popular is the Name Sienna?
Sienna ranked 94th among US girls in 2025, its best rank in the 56 years it has appeared in federal birth records, with 2,659 babies given the name that year (3).
The shape of that climb is unusual. Sienna first appears in the data in 1960 and spent three decades as a genuine rarity, broke into the top 1,000 in the mid-1990s, then rose steeply through the 2000s. What it has not done is level off: its peak year and best rank are both the most recent year of data.
For a parent choosing now, two things follow. The name cannot sound dated, because its entire run is recent. In Social Security Administration data, half of everyone ever recorded as Sienna was born after 2014, and 39,877 girls carry it across the whole record.
It also is not crowded yet. About one girl in every 605 born in 2025 was named Sienna, so your daughter will run into another one eventually, but rarely in her own class. If the current direction holds she will meet more of them than you would expect from the name’s history, which is the trade for picking something on the way up.
Names That Moved With Sienna
Set Sienna’s yearly numbers against every other girls’ name over the last 45 years and a small group comes back whose curves rise and fall on the same schedule. These are not sound-alikes. They are the names a parent drawn to Sienna tends to be weighing in the same season, and every one of them is rising in the most recent year of data. The three closest are plotted below.
- Sienna
- Liliana
- Alina
- Phoebe
- Liliana: The closest match of the group. It reached its own best rank, 78th, in 2025 and is still climbing, the same late-peaking pattern Sienna has.
- Alina: Best rank 130th in 2025, and rising. It sits a little further down the list than Sienna but is on the same upward line.
- Phoebe: Best rank 157th in 2025, also rising. The rarest of the three plotted names, and the one that still reads as a discovery.
- Naomi: Not plotted, but close behind: best rank 44th in 2023, 47th in 2025.
- Lucy: Best rank 25th in 2025, and rising.
- Ruby: Another color name, and proof this taste cluster is not limited to newer names. It ranked 23rd in 1913, at the very start of the comparable data, and sits 64th in 2025, still rising.
How Do I Pronounce Sienna?
Sienna is pronounced see-EN-uh, three syllables with the stress on the middle one.
Because the spelling is phonetic, mispronunciations are rare and short-lived. You may occasionally hear a rushed two-syllable see-NAH, but the three-syllable English form is what teachers and coaches will land on without being told.
Is Sienna a Boy or Girl Name?
Sienna is a girls’ name in US records, and lopsidedly so. Ten boys have ever been recorded with it, five of them in a single year, 2011, and none at all in the most recent year of data, against nearly 40,000 girls.
The sound is the reason. Place names and color names are theoretically open to either sex, but the closing -a is read as feminine in English naming habits, and Sienna has never fought that.
In Italy the place name itself carries no gender at all. If you like the sound for a boy, Latin boy names are the better hunting ground, or the spelling Senna, which lands harder.
Variations of Sienna
Sienna is the English spelling of both the pigment and the name, and a few close relatives travel with it:
- Siena: The Italian spelling, and the city’s own. One N, same sound, a cleaner look on paper.
- Senna: A separate botanical name, a flowering shrub, that happens to sit right next door in sound.
- Cienna: Swaps the S for a soft C and keeps the pronunciation intact.
Worth knowing before you choose: the one-N Siena will be corrected to two by anyone who knows the color, and the two-N Sienna will be corrected to one by anyone who has been to Tuscany. Either way, expect a lifetime of gentle amendments.
Nicknames for Sienna
Sienna is a short name that does not need shortening, but families shorten everything, so here is what tends to stick:

- Sisi / CeCe: Softer and a little vintage, good for a small child.
- Enna: Drops the S instead of the ending, which makes it feel like a different name entirely.
- Nenna: Rhythmic and playful, usually a toddler-sibling invention.

- Sia: The shortest form that still sounds like the whole name.

Sibling Names for Sienna

Sienna in Pop Culture
