The most common way to say “youngest” in Spanish is el/la menor, with el/la más joven as another safe pick.
If you’re trying to say “youngest” in Spanish, you’ve got a couple of great options. The trick is picking the one that matches what you mean in English. Are you talking about the youngest person in a group? The youngest sibling? Or just someone who’s younger than someone else?
This article gives you the phrases Spanish speakers use most, the grammar you need to make them sound natural, and plenty of plug-and-play sentences you can steal.
What “Youngest” Means In Spanish
English uses “youngest” in a few ways. Spanish often separates those meanings:
- Youngest in a group: the youngest sibling, the youngest student, the youngest teammate.
- Younger than someone else: younger than her sister, younger than the new hire.
- Youngest child: “the baby of the family,” even when they’re grown.
Once you know which meaning you want, the Spanish choice gets easy.
How To Say Youngest In Spanish In Real Sentences
The two most reliable translations are el/la menor and el/la más joven. Both are normal. Both show up a lot. One often feels more “default” than the other.
Use El/la menor For “The Youngest” In A Set
El/la menor is the everyday pick for “the youngest.” It fits family talk, school talk, and most group comparisons.
- Él es el menor de tres hermanos. (He’s the youngest of three siblings.)
- Ella es la menor del grupo. (She’s the youngest in the group.)
- Somos los menores de la clase. (We’re the youngest in the class.)
Notice how Spanish often makes the group explicit with de or del/de la. That small piece keeps the sentence clear.
Use El/la más joven When Age Is The Main Point
El/la más joven is also natural. It leans into age more directly, and it’s a great choice when you want the reader or listener to hear “age” right away.
- De todos, Marta es la más joven. (Of everyone, Marta is the youngest.)
- Mi tío es el más joven de sus hermanos. (My uncle is the youngest of his siblings.)
- Ella fue la más joven en ganar el premio. (She was the youngest to win the award.)
If you’re unsure, el/la menor is a strong default for “the youngest.” If you want a more direct “young by age” feel, go with el/la más joven.
Grammar That Keeps Your Sentence Clean
Gender And Number With Menor
Menor doesn’t change its ending. The article does the work:
- el menor (youngest male / youngest boy)
- la menor (youngest female / youngest girl)
- los menores (the youngest ones, mixed or male group)
- las menores (the youngest ones, all female group)
Agreement With Más joven
Joven has a plural form: jóvenes. That’s where many learners slip.
- Él es el más joven. / Ella es la más joven.
- Ellos son los más jóvenes. / Ellas son las más jóvenes.
“Youngest Of” With De
These patterns cover most “youngest of …” sentences:
- el/la menor de + plural → la menor de mis primas
- el/la menor del/de la + group → el menor del equipo
- el/la más joven de + group → la más joven de la oficina
If your sentence feels unfinished, adding the group after de often fixes it.
Menor Vs Más joven Vs “Younger”
Here’s a point that saves people from awkward mistakes: más joven can mean “younger,” not “youngest,” unless you build the full superlative with el/la.
“Younger Than”
- Ana es más joven que Laura. (Ana is younger than Laura.)
“The Youngest”
- Ana es la más joven. (Ana is the youngest.)
That little la (or el) changes the meaning. Without it, you’re often saying “younger,” not “youngest.”
Where To Place Menor In A Sentence
Menor can work in two common spots, and the meaning can shift a bit depending on the structure.
El/la menor As A Standalone Label
This is the clean “the youngest” label:
- Mi hermana es la menor. (My sister is the youngest.)
- ¿Tú eres el menor? (Are you the youngest?)
Hermano menor As “Younger Brother”
Mi hermano menor often means “my younger brother,” which is not always the same as “my youngest brother.” If you have two brothers, “younger brother” and “youngest brother” match. If you have three, “younger brother” can point to the one younger than you, not the youngest overall.
- Mi hermano menor vive en Valencia. (My younger brother lives in Valencia.)
- Mi hermano es el menor de todos. (My brother is the youngest of all.)
If your goal is “youngest,” el/la menor plus the group makes the meaning unmistakable.
More Natural Options You’ll Hear
Benjamín / Benjamina For The Youngest Child
You may hear el benjamín (or la benjamina) for “the youngest (family member/kid).” It’s informal and a bit playful. It’s used in Spain and also in parts of Latin America.
- Soy el benjamín de la familia. (I’m the youngest in the family.)
- Ella es la benjamina de sus hermanos. (She’s the youngest of her siblings.)
In formal writing, stick with el/la menor or el/la más joven.
El/la más pequeño/a When “Smallest” Is Part Of The Meaning
Pequeño/a can refer to age, size, or both. If you say la más pequeña, some listeners will hear “the smallest” before “the youngest.” That’s fine when size is part of what you mean.
- Es la más pequeña de los hermanos. (She’s the youngest / the smallest of the siblings.)
If you only mean age, menor or más joven stays clearer.
Table Of Options By Situation
This table helps you pick a phrase fast without second-guessing.

| Youngest child (casual label) | el benjamín / la benjamina | Informal tone; not for formal text. |
| Youngest daughter/son | la hija menor / el hijo menor | Good when you want the noun stated. |
| “My youngest is 8” | El/la menor tiene ocho años. | Common family phrasing. |
| When “smallest” is meant too | el/la más pequeño/a | Leans toward size; use on purpose. |

Mistakes That Make Your Spanish Sound Off
Forgetting The Article With Más joven
Without el/la, you may be saying “younger,” not “youngest.” Compare these:
- Mi hermano es más joven que yo. (My brother is younger than me.)
- Mi hermano es el más joven. (My brother is the youngest.)
Using Pequeño/a For Adults
Pequeño/a works well for kids and can work for adults in a playful tone. In neutral writing about adults, it can sound childish.
- Es el menor de la familia. (neutral)
- Es el más joven de la familia. (neutral)
- Es el más pequeño de la familia. (may lean toward size or a kid-like tone)
Mixing Up “Youngest” And “Minor”
Menor can also mean “minor” in legal or administrative contexts. The phrase around it usually makes the meaning clear, yet it’s good to know why you may see it in forms.
- menor de edad (underage)
- el menor de la familia (the youngest in the family)
If you’re describing people in a group, el/la menor reads as “youngest” in normal conversation.
