万圣节前夕(英语：Halloween，为“All Hallows' Eve”的缩写)，在每年的10月31日，是西方世界的传统节日，主要流行于撒克逊人后裔云集的美国、不列颠群岛、澳大利亚、加拿大和新西兰等西方国家。当晚小孩会穿上化妆服，戴上面具，挨家挨户收集糖果等。
万圣夜是诸圣节(All Hallows' Day)的前夜。其英语名称中的“Hallow”源于中古英语的“halwen”，与“holy”词源很接近，在苏格兰和加拿大的某些区域，诸圣节仍然被称为“Allhallowmas”，意思是在纪念所有圣人(All Hallows)的那一天要举行的弥撒(Mass)。
万圣节通常与灵异的事物联系起来。欧洲传统上认为万圣夜是鬼怪世界最接近人间的时间，这传说与东亚的中元节与盂兰节类似。美国明尼苏达州的阿诺卡(Anoka)号称是“世界万圣节之都”，每年都举行大型的巡游庆祝。
《Monster Mash》
- Bobby Pickett
I was working in the lab, late one night
When my eyes beheld an eerie sight
For my monster from his slab, began to rise
And suddenly to my surprise
He did the mash, he did the monster mash
The monster mash, it was a graveyard smash
He did the mash, it caught on in a flash
He did the mash, he did the monster mash
From my laboratory in the castle east
To the master bedroom where the vampires feast
The ghouls all came from their humble abodes
To get a jolt from my electrodes
They did the mash, they did the monster mash
The monster mash, it was a graveyard smash
They did the mash, it caught on in a flash
They did the mash, they did the monster mash
The zombies were having fun
The party had just begun
The guests included Wolfman,
Dracula, and his son
The scene was rockin', all were digging the sounds
Igor on chains, backed by his baying hounds
The coffin-bangers were about to arrive
With their vocal group, 'The Crypt-Kicker Five'
They played the mash, they played the monster mash
The monster mash, it was a graveyard smash
They played the mash, it caught on in a flash
They played the mash, they played the monster mash
Out from his coffin, Drac's voice did ring
Seems he was troubled by just one thing
Opened the lid and shook his fist and said
"Whatever happened to my Transylvania Twist? "
It's now the mash, it's now the monster mash
The monster mash, it was graveyard smash
It's now the mash, it caught on in a flash
It's now the mash, it's now the monster mash
Now everything's cool, Drac's a part of the band
And my Monster Mash is the hit of the land
For you, the living, this mash was meant too
When you get to my door, tell them Boris sent you
Then you can mash, then you can monster mash
The monster mash, and do my graveyard smash
Then you can mash, you'll catch on in a flash
Then you can mash, then you can monster mash
