Return of the living dead. There’s definitely much better ones, but this is my favorite.

Train to Busan. By a mile. Best zombie movie hands down. I’ll die on this hill.

Honourable mentions:

OG Dawn of the Dead is special and will always hold a top spot.

28 Days Later & 28 Weeks are both top notch.

And I’ll catch heat for this, but World War Z is an excellent zombie movie. And I say that as a fan of the book who is disappointed we didn’t get a faithful adaptation. But if you take the movie as a stand alone, unaffiliated, zombie flick, it’s better than just good.

Shaun of the Dead

Everyone had their own ideas for zombie movies but to me zombies are very campy so my vote is Zombieland.

The original Dawn of the Dead, with Night of the Living Dead, Braindead, Fido, Reanimator, Black Sheep, and Cemetery Man all being close contenders.

Ooooo, if I sit and think about this one, I’ll be completely unable to settle on a single pick, so I’m just going with my knee jerk reaction. Return of the Living Dead perfectly hits the intersection of comedy and horror that I like out of my zombie media.

Braindead/Dead Alive UR or 28 Weeks Later.
