Leo Baby Names: 40 Radiant Names for Your Fire Sign Baby

Born between July 23 and August 22, your little Leo is the radiant, warm-hearted star of the zodiac. Ruled by the Sun itself (the only sign ruled by a star, not a planet) and symbolized by the regal Lion, Leo babies are wired to shine: they're confident, generous, dramatic, loyal, and naturally magnetic — born performers and leaders with enormous, golden hearts. Where Aries is fiery-bold, Leo is fiery-radiant: sunny, proud, and impossible to ignore. So a Leo suits a name with real presence — something bold, warm, and a little majestic, befitting the lion-hearted little royal you're naming.

This guide gathers 40 radiant names that capture the Leo spirit — sunny, regal, and lion-hearted — for girls and boys, drawing on the Sun, lions, gold, royalty, and warmth. Whether you want a name that blazes or one that quietly glows, let's find the perfect match for your little lion.

The Leo personality (and what suits it)

The Leo traits point clearly toward bold, warm, regal names:

• Confident & magnetic — strong, standout names with real presence (Leo can carry a big name).
• Sun-ruled — sun, light, and golden names echo their radiant ruler.
• Lion-hearted — names meaning lion or courage are a perfect, literal fit.
• Regal & proud — royal, noble names suit the zodiac's natural king/queen.
• Warm & generous — golden, joyful names that radiate warmth.

So the ideal Leo name is radiant and regal — bold, sunny, and a little majestic, matching that golden, show-stopping lion heart.

☀️ Leo girl names

Radiant, warm, and regal:

Leona (lioness — the literal feminine Leo!), Soleil (sun), Aurelia (the golden one), Aurora (dawn, golden light), Scarlett (fiery, bold), Regina (queen), Goldie (golden), Seraphina (fiery, radiant), Roxana (dawn), Leonie (lioness), Helena (bright, shining light), Stella (star — Leo loves to shine), Cleo (glory — and Cleopatra, a regal Leo icon), Marigold (the golden sun-flower).

Leona, Soleil, and Aurelia are the standouts — Leona literally meaning "lioness," Soleil meaning "sun," Aurelia meaning "golden." Cleo and Regina bring the regal Leo majesty (Cleopatra herself was the ultimate Leo).

☀️ Leo boy names

Bold, sunny, and lion-hearted:

Leo (lion — the sign itself!), Leon/Leonardo (lion-strong), Sol (the sun), Elio/Helios (sun), Apollo (sun god), Aslan (lion), Rex (king), Augustus (majestic, revered — and a famous Leo emperor), Cyrus (sun, lord), Ari (lion), Caleb (whole-hearted, bold), Samson (like the sun), Magnus (great), Royce/Roy (king).

Leo, Leon, and Aslan are the standouts — all meaning "lion," the sign's very symbol (Leo being the most beloved). Sol, Elio, and Apollo capture the sun rulership, and Rex/Augustus the regal majesty.

Names by Leo trait

Match the name to the quality you most see in your little lion:

• For the lion-hearted (the symbol): Leo, Leona, Leon, Aslan, Ari, Leonardo.
• For the sun-ruled radiance: Soleil, Sol, Elio, Apollo, Aurelia (golden), Helena.
• For the regal, proud one: Regina (queen), Rex (king), Augustus, Cleo, Royce.
• For the warm, generous heart: Goldie, Aurelia, Marigold, Stella — sunny and bright.

Leo is the only sign ruled by the Sun and the only one symbolized by such a regal animal, so it has the richest "literal" naming options of the zodiac: you can choose an actual lion name (Leo, Leona), an actual sun name (Soleil, Sol), or a royal name (Regina, Rex) and hit the theme perfectly.

The Sun and the Lion: born to shine

Here's what makes Leo so special for a bold name: Leo is the fixed fire sign, ruled by the Sun — and the Sun is the center around which everything orbits. Astrologically, Leo is wired to be seen, to lead with warmth, and to light up every room. "Fixed" adds loyalty and steadiness to that fire, so a Leo isn't just flashy — they're a warm, dependable presence whose light lasts.

This gives a lovely naming spirit: a Leo can carry a big, radiant name that a shyer sign might find too much. A Leo named Apollo, Regina, or Leonardo grows into the grandeur — the name and the personality rise to meet each other. So if you've ever loved a name but feared it was "too bold," a Leo baby is exactly the one who can wear it with a smile. The Leo naming sweet spot is radiant confidence — a name that shines as warmly and unapologetically as the little sun you're raising.

Honest tips before you choose

• Leo can carry a grand name — this is the sign for that bold, regal, radiant name you love but worried was "too much." A Leo wears it beautifully.
• You don't have to go literal — a name simply meaning golden, warm, or bright (Aurelia, Helena, Goldie) captures Leo's sunny spirit without spelling out "lion" or "sun."
• August Leos can nod to August birth-themes too (peridot birthstone, the sunflower/gladiolus) for a layered summer-baby connection.

Born on the cusp? And a birthstone bonus

If your baby arrives in the first days of Leo (around July 23), they're on the Cancer–Leo cusp — a tender-meets-radiant blend, so you might pair a bold name with a gentle, moonlit middle. Late Leo (mid-August) edges toward Virgo, adding a thoughtful, refined streak to the lion's roar.

Leo also gets some gorgeous birth-theme layers to play with. Most Leos are born in August, whose birthstone is the green-gold peridot (light and warmth) and whose birth flowers are the sunflower and gladiolus — both radiant, sun-following blooms that couldn't suit a sun-ruled lion better. A little Leo with a Marigold, Sunny, or golden-themed middle name ties the sign and the high-summer season together beautifully. And since Leo is the warmest, most generous sign, names that simply radiate — sunny sounds, golden meanings, big-hearted warmth — will always feel right, whether you nod to the calendar or not. The goal is a name that glows: as warm, proud, and golden as the little sun you're raising at the brightest time of the year.

Pairings and sibling sets

Middle names that flow: Leona Rose, Leo James, Soleil Mae, Apollo Reed, Aurelia Grace, Rex Oliver.

Sibling sets: a Leo sun name pairs gorgeously with a Cancer or Pisces moon name (Apollo & Luna — sun and moon!), or with another fire-sign (Aries, Sagittarius) name for a bold zodiac theme. Sun-and-moon siblings are an especially beautiful pairing.
