I love all horror movies, including Christmas ones. My favorite is probably A Christmas Horror Story with William Shatner. It was on Netflix last year; I’m hoping it comes back for the upcoming season.
Yeah, it’s not the most advertised, or commercially viable sub-genre… something about ruining Santa Claus for kids, the li’l twerps.
But they’re out there, and if you want 'em bad enough, you’ll find 'em. There’s a couple stinkers, but most are actually good… at least as far as horror movies go. I’ll vouch for all on my list.

Rachel Nichols works too late on Christmas Eve and gets taken hostage by the insane garage attendant. Comme ci comme ça.
Wind Chill
College kids ride-share home for Christmas but get stuck on an abandoned road. I liked it a lot, but I’ve always been a big fan of Emily Blunt so my opinion may be skewed.
Plus several of the ones already mentioned in this thread. How much do I love Christmas horror movies? I’ll soon be watching Anna and the Apocalypse even though I despise musicals.
Googling around to jog my memory of others I’ve seen:
The Children (2009)
The family Christmas holiday takes a turn when all the young kids turn into murderous psychopaths. I’ve seen this at least twice; good murdery fun. (It’s not a comedy in any way.)
That same googling turned up the following as highly recommend, but I haven’t seen it. Note: The recommendations make a point to not say anything about it for fear of spoiling it.
Dead End (2003)
Leads are Ray Wise and Lyn Shaye? Sold!
