How Many Brothers Does Alec Baldwin Have? The Truth About the Baldwin Dynasty

If you’ve ever turned on a TV and felt like you were seeing a Baldwin in every other movie, you aren’t imagining things. The Baldwin family is basically Hollywood’s version of a sports franchise, but instead of jerseys, they wear leather jackets and piercing blue-eyed stares. People are always asking, how many brothers does Alec Baldwin have, usually because they’ve just spotted "the other one" in an old 90s thriller or a reality show.

Alec is the oldest. He’s the one we know from 30 Rock and those SNL sketches. But he isn’t a solo act.

The Magic Number: Alec’s Three Brothers

Alec Baldwin has three younger brothers. All of them—Daniel, William (Billy), and Stephen—are actors.

It’s actually pretty wild when you think about it. Most families have one kid who wants to be a star while the others become accountants or teachers. Not this group. They grew up in a rowdy, Irish-Catholic household in Massapequa, Long Island, and one by one, they all decided to chase the spotlight.

Their father, Alexander Rae Baldwin Jr., was a high school teacher and football coach. He was apparently a tough guy, the kind of dad who instilled a massive amount of drive in his boys. Their mom, Carol, became a legendary figure in her own right for her work with breast cancer research before she passed away in 2022.

Daniel Baldwin: The Second Son

Daniel is the brother right after Alec. Born in 1960, he’s probably most famous for his role as Detective Beau Felton on Homicide: Life on the Street.

He’s had a bit of a rougher road than the others. Daniel has been very open about his struggles with addiction, even appearing on Celebrity Rehab with Dr. Drew back in the day. He’s done a ton of work in the indie film scene and has directed a documentary called My Promise to PJ, which actually features all four brothers together. That’s a rare sight.

William "Billy" Baldwin: The Heartthrob

Then there’s Billy. If you grew up in the 90s, Billy Baldwin was everywhere. He was the "pretty" one—though honestly, they all have that same jawline.

Billy was a Calvin Klein model before he hit it big in movies like Flatliners, Backdraft, and Sliver. He’s been married to Chynna Phillips (from Wilson Phillips) since 1995, which is basically an eternity in celebrity years. He’s also the one you might have spotted in Gossip Girl playing Serena van der Woodsen’s dad.

Stephen Baldwin: The Youngest and the "Rebel"

Stephen is the baby of the brothers, born in 1966. You’d know him from The Usual Suspects or Bio-Dome.

Stephen took a bit of a different path later in life. He became a born-again Christian and is quite active in political circles. He’s also the father of Hailey Bieber. Yep, that means Alec is Justin Bieber’s uncle-in-law. It’s a small world in Hollywood, but the Baldwin family tree makes it feel even smaller.

Wait, There are Sisters Too?

People forget this. While the "Baldwin Brothers" is the brand, Alec actually has two sisters.

1. Elizabeth Keuchler: She’s the eldest of the entire bunch. She generally stays out of the limelight and has spent her time involved with the family’s charitable foundations.
2. Jane Sasso: She’s the second youngest, tucked in between Billy and Stephen.

So, in total, there are six siblings. Four boys, two girls.

Why Do They All Look So Alike?

It’s the genetics. Seriously. They have this very specific "Baldwin look"—the squinty eyes, the raspy voice, and that "I’m about to give a dramatic monologue" energy.

Back in the 90s, the term "Baldwin" was actually used as slang in the movie Clueless to describe a really hot guy. That tells you everything you need to know about their cultural peak.

What the Baldwin Brothers Are Doing Now

Alec is still the most prominent, though he’s been through a massive amount of legal and personal turmoil recently following the Rust tragedy. He recently announced a new reality show with his wife Hilaria and their seven (yes, seven) young children.

The brothers haven't always seen eye-to-eye. Stephen and Alec, in particular, have had very public disagreements about politics over the years. Honestly, it’s just like any other big family, except their Thanksgiving arguments end up on Page Six.

Summary Checklist of the Baldwin Brothers

If you’re trying to keep them straight for a trivia night, here’s the quick breakdown:

• Alec: The oldest, 30 Rock, most famous.
• Daniel: Second oldest, Homicide: Life on the Street, filmmaker.
• Billy: The middle brother, Backdraft, married to Chynna Phillips.
• Stephen: The youngest, The Usual Suspects, Hailey Bieber’s dad.

Actionable Insight: How to Tell Them Apart

If you see a Baldwin and you're not sure which one it is, look at the chin. Alec has the most prominent "leading man" square jaw. Billy has a softer, more "model-like" face. Daniel is usually a bit stockier and more rugged. Stephen has the most "mischievous" look—he often looks like he’s about to tell a joke or a secret.

Next time you're scrolling through Netflix and see a familiar name in the credits, check the first name. Chances are, it's one of these four.

If you're curious about the next generation of this family, you can look into the careers of Ireland Baldwin (Alec's oldest) or Hailey Bieber (Stephen's daughter), who have both managed to keep the family name alive in the fashion world.
